American Society for Therapeutic Radiology and Oncology (ASTRO) Emerging Technology Committee Report on Electronic Brachytherapy  

SciTech Connect

The development of novel technologies for the safe and effective delivery of radiation is critical to advancing the field of radiation oncology. The Emerging Technology Committee of the American Society for Therapeutic Radiology and Oncology appointed a Task Group within its Evaluation Subcommittee to evaluate new electronic brachytherapy methods that are being developed for, or are already in, clinical use. The Task Group evaluated two devices, the Axxent Electronic Brachytherapy System by Xoft, Inc. (Fremont, CA), and the Intrabeam Photon Radiosurgery Device by Carl Zeiss Surgical (Oberkochen, Germany). These devices are designed to deliver electronically generated radiation, and because of their relatively low energy output, they do not fall under existing regulatory scrutiny of radioactive sources that are used for conventional radioisotope brachytherapy. This report provides a descriptive overview of the technologies, current and future projected applications, comparison of competing technologies, potential impact, and potential safety issues. The full Emerging Technology Committee report is available on the American Society for Therapeutic Radiology and Oncology Web site.

The American Society for Radiation Oncology's 2010 Core Physics Curriculum for Radiation Oncology Residents  

SciTech Connect

Purpose: In 2004, the American Society for Radiation Oncology (ASTRO) published its first physics education curriculum for residents, which was updated in 2007. A committee composed of physicists and physicians from various residency program teaching institutions was reconvened again to update the curriculum in 2009. Methods and Materials: Members of this committee have associations with ASTRO, the American Association of Physicists in Medicine, the Association of Residents in Radiation Oncology, the American Board of Radiology (ABR), and the American College of Radiology. Members reviewed and updated assigned subjects from the last curriculum. The updated curriculum was carefully reviewed by a representative from the ABR and other physics and clinical experts. Results: The new curriculum resulted in a recommended 56-h course, excluding initial orientation. Learning objectives are provided for each subject area, and a detailed outline of material to be covered is given for each lecture hour. Some recent changes in the curriculum include the addition of Radiation Incidents and Bioterrorism Response Training as a subject and updates that reflect new treatment techniques and modalities in a number of core subjects. The new curriculum was approved by the ASTRO board in April 2010. We anticipate that physicists will use this curriculum for structuring their teaching programs, and subsequently the ABR will adopt this educational program for its written examination. Currently, the American College of Radiology uses the ASTRO curriculum for their training examination topics.

Kokes Awards for the 22nd North American Catalysis Society Meeting, June 5-10, 2011  

SciTech Connect

The biennial North American Catalysis Society (NACS) Meetings are the premiere conferences in the area of catalysis, surface science, and reaction engineering. The 22nd meeting will be held the week of June 5-10, 2011 in Detroit, Michigan. The objective of the Meetings is to bring together leading researchers for intensive scientific exchange and interactions. Financial support that offsets some of the associated costs (specifically, registration fee, airline tickets, and hotel accommodations) would encourage graduate students, and for the first time undergraduate students, to attend and participate meaningfully in this conference. The funds sought in this proposal will help support the Richard J. Kokes Travel Award program. Graduate students eligible for these merit-based Awards are those who study at a North American university and who will present at the Meeting. We have currently 209 applications and we expect to be able to fund about half of them. The NACS has traditionally sought to encourage graduate student, and this year for the first time undergraduate studies, participation at the National Meetings and providing financial support is the most effective means to do so. Their attendance would contribute significantly to their scientific training and communication and presentation skills. They would be exposed to the leading researchers from the US and abroad; they would meet their peers from other universities; they would learn about cutting-edge results that could benefit their research projects; and they may become interested in becoming active participants in the catalysis community. These young investigators represent the next generation of scientists and engineers, and their proper training will lead to future scientific breakthroughs and technological innovations that benefit the US economy. Advances in catalysis can come in the form of more energy-efficient and environmentally-friendly chemical processes, improved fuel cell performance, efficient hydrogen production, and a cleaner environment.

Report to the American Physical Society by the study group on nuclear fuel cycles and waste management  

SciTech Connect

Utilization of nuclear fuels and management of nuclear wastes have become major topics of public discussion. Under the auspices of the American Physical Society this study was undertaken as an independent evaluation of technical issues in the use of fissionable materials in nuclear fuel cycles, together with their principal economic, environmental, health and safety implications. Reprocessing and recycling in light water reactors were examined, along with technical measures proposed as possible safeguards; advanced reactor fuel cycles were also studied for their resource and safeguards implications. Much of the work of the group centered on the principal alternatives for disposal of radioactive wastes and control of effluents. The group examined the research and development programs sponsored by government agencies along with associated relationships among agencies and between government and private industry. Available information was also considered on nuclear fuel resources, and on important economic and environmental aspects of the various fuel cycles in order to strive for a balanced comparative study. The report presents many conclusions on various aspects of the nuclear fuel cycles and also provides recommendations concerning present utilization and future improvement of fuel cycle technology.

Local Control, Toxicity, and Cosmesis in Women >70 Years Enrolled in the American Society of Breast Surgeons Accelerated Partial Breast Irradiation Registry Trial  

SciTech Connect

Purpose: The American Society of Breast Surgeons enrolled women in a registry trial to prospectively study patients treated with the MammoSite Radiation Therapy System breast brachytherapy device. The present report examined the outcomes in women aged >70 years enrolled in the trial. Methods and Materials: A total of 1,449 primary early stage breast cancers were treated in 1,440 women. Of these, 537 occurred in women >70 years old. Fisher's exact test was performed to correlate age ({<=}70 vs. >70 years) with toxicity and with cosmesis. The association of age with local recurrence (LR) failure times was investigated by fitting a parametric model. Results: Older women were less likely to develop telangiectasias than younger women (7.9% vs. 12.4%, p = 0.0083). The incidence of other toxicities was similar. Cosmesis was good or excellent in 92% of the women >70 years old. No significant difference was found in LR as a function of age. The 5-year actuarial LR rate with invasive disease for the older vs. younger population was 2.79% and 2.92%, respectively (p = 0.5780). In women >70 years with hormone-sensitive tumors {<=}2 cm who received hormonal therapy (n = 195), the 5-year actuarial rate of LR, overall survival, disease-free survival, and cause-specific survival was 2.06%, 89.3%, 87%, and 97.5%, respectively. These outcomes were similar in women who did not receive hormonal therapy. Women with small, estrogen receptor-negative disease had worse LR, overall survival, and disease-free survival compared with receptor-positive patients. Conclusions: Accelerated partial breast irradiation with the MammoSite radiation therapy system resulted in low toxicity and produced similar cosmesis and local control at 5 years in women >70 years compared with younger women. This treatment should be considered as an alternative to omitting adjuvant radiotherapy for older women with small-volume, early-stage breast cancer.

The Status and future of ground-based TeV gamma-ray astronomy. A White Paper prepared for the Division of Astrophysics of the American Physical Society  

E-Print Network (OSTI)

In recent years, ground-based TeV gamma-ray observatories have made spectacular discoveries including imaging spectroscopy observations of galactic sources of different classes, and the discovery of rapid gamma-ray flares from radio galaxies and active galactic nuclei containing supermassive black holes. These discoveries, and the fact that gamma-ray astronomy has the potential to map the radiation from dark matter annihilation in our Galaxy and in extragalactic systems, have attracted the attention of the wider scientific community. The Division of Astrophysics of the American Physical Society requested the preparation of a white paper on the status and future of ground-based gamma-ray astronomy to define the science goals of a future observatory, to determine the performance specifications, to identify the areas of necessary technology development, and to lay out a clear path for proceeding beyond the near term.

Ceramic fiber ceramic matrix filter development  

SciTech Connect

The objectives of this project were to develop a novel type of candle filter based on a ceramic fiber-ceramic matrix composite material, and to extend the development to full-size, 60-mm OD by 1-meter-long candle filters. The goal is to develop a ceramic filter suitable for use in a variety of fossil energy system environments such as integrated coal gasification combined cycles (IGCC), pressurized fluidized-bed combustion (PFBC), and other advanced coal combustion environments. Further, the ceramic fiber ceramic matrix composite filter, hereinafter referred to as the ceramic composite filter, was to be inherently crack resistant, a property not found in conventional monolithic ceramic candle filters, such as those fabricated from clay-bonded silicon carbide. Finally, the adequacy of the filters in the fossil energy system environments is to be proven through simulated and in-plant tests.

# 2005 British Occupational Hygiene Society Published by Oxford University Press doi:10.1093/annhyg/meh098 Survey of the Biological Effects of Refractory Ceramic Fibres: Overload and Its Possible Consequences  

E-Print Network (OSTI)

This paper summarizes the biological effects of refractory ceramic fibres (RCFs). RCFs are aluminosilicate glass insulation wools with similar chemical properties to other synthetic vitreous fibres (SVFs) or man-made vitreous fibres (MMVFs). There is concern that RCFs could be significantly more pathogenic than other SVFs. This paper critically reviews the data on which this perception is based. Morbidity studies on workers in RCF manufacturing indicated that, in the United states, RCF exposure was associated with an increased incidence of pleural plaques and in both the united states and Europe with statistically significant changes in some measures of lung function (though not at present exposure levels). No interstitial fibrosis was found. An ongoing mortality study of limited statistical power has failed to indicate any increased incidence of lung cancer or mesothelioma. Findings in several early animal studies led to a large series of inhalation studies where rats exposed to high levels of RCF developed fibrosis and tumours but not those exposed to other SVFs. Similarly hamsters exposed to one sample (RCF1) developed mesothelioma. Subsequent analyses of the data indicated that the RCF used in these experiments had a significantly greater proportion of non-fibrous particles than those present in the other types of SVFs tested or in workplace air. Short-term studies indicated that

Ceramic Technology Project  

DOE Green Energy (OSTI)

The Ceramic Technology Project was developed by the USDOE Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS's Materials Development Program, was developed to meet the ceramic technology requirements of the OTS's automotive technology programs. Significant accomplishments in fabricating ceramic components for the USDOE and NASA advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. A five-year project plan was developed with extensive input from private industry. In July 1990 the original plan was updated through the estimated completion of development in 1993. The objective is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on the structural ceramics for advanced gas turbine and diesel engines, ceramic bearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities.

Coated ceramic breeder materials  

DOE Patents (OSTI)

A lithium containing ceramic breeder material is described which is coated with a neutron multiplier such as Beryllium (Be), Beryllium Oxide (BeO), or other material having a higher thermal conductivity than the lithium ceramic material itself. In addition to exhibiting certain thermal conductivity properties, the neutron multiplier must be capable of withstanding the high temperatures (700/sup 0/ to 1300/sup 0/K) experienced in a breeder blanket of a fusion reactor. State of the art considerations have indicated several possible configurations for the lithium containing ceramic breeders, including a sphere-pac arrangement or sintered pellets or blocks. When one adds a neutron multiplier such as Be or BeO into a sphere-pac bed of lithium containing ceramic breeders, current concepts include mixing the neutron multiplier randomly into the sphere-pac bed in the form of small spheres of a size comparable to that of the lithium ceramic particles. The present invention shows that a sphere-pac bed of breeder particles coated with a neutron multiplier such as Be and BeO has an improved thermal conductivity when compared with that of a bed of uncoated breeder particles randomly mixed with Be or BeO spheres having the same breeder/multiplier composition ratio.

Ceramic transactions: Ceramic joining. Volume 77  

Science Conference Proceedings (OSTI)

The advent of new materials for engineering applications almost always brings a new challenge: how will these new materials be joined to a larger engineering structure? New ceramic materials are being developed for a wide variety of applications in areas such as power generation, energy conversion, automotive and aerospace, with specific applications including heat exchangers, fuel cells, turbocharger rotors, combustor liners, and for many other applications. Typically the new materials will be exposed to more hostile environments with respect to temperature, corrosion, and stress than materials in the past, and thus, many of the conventional joining techniques developed for less hostile environments do not work. Understanding fundamental issues in joining enables the development of new techniques to be able to utilize new materials. A previous DOE workshop defined fundamental and critical issues in ceramic joining and classified them into four general areas: joining techniques; joint failure; residual stress; and characterization and testing. The present international symposium is an effort to discuss some of these fundamental issues and to define areas for future research. Separate abstracts have been indexed into the energy database for articles from this symposium.

Ceramics for fusion applications  

SciTech Connect

Ceramics are required for a variety of uses in both near-term fusion devices and in commercial powerplants. These materials must retain adequate structural and electrical properties under conditions of neutron, particle, and ionizing irradiation; thermal and applied stresses; and physical and chemical sputtering. Ceramics such as Al/sub 2/O/sub 3/, MgAl/sub 2/O/sub 4/, BeO, Si/sub 3/N/sub 4/ and SiC are currently under study for fusion applications, and results to date show widely-varying response to the fusion environment. Materials can be identified today which will meet initial operating requirements, but improvements in physical properties are needed to achieve satisfactory lifetimes for critical applications.

Ceramic stationary gas turbine  

DOE Green Energy (OSTI)

The performance of current industrial gas turbines is limited by the temperature and strength capabilities of the metallic structural materials in the engine hot section. Because of their superior high-temperature strength and durability, ceramics can be used as structural materials for hot section components (blades, nozzles, combustor liners) in innovative designs at increased turbine firing temperatures. The benefits include the ability to increase the turbine inlet temperature (TIT) to about 1200{degrees}C ({approx}2200{degrees}F) or more with uncooled ceramics. It has been projected that fully optimized stationary gas turbines would have a {approx}20 percent gain in thermal efficiency and {approx}40 percent gain in output power in simple cycle compared to all metal-engines with air-cooled components. Annual fuel savings in cogeneration in the U.S. would be on the order of 0.2 Quad by 2010. Emissions reductions to under 10 ppmv NO{sub x} are also forecast. This paper describes the progress on a three-phase, 6-year program sponsored by the U.S. Department of Energy, Office of Industrial Technologies, to achieve significant performance improvements and emissions reductions in stationary gas turbines by replacing metallic hot section components with ceramic parts. Progress is being reported for the period September 1, 1994, through September 30, 1995.

DOE Green Energy (OSTI)

This project is separated into three tasks. The first task is a design and modeling effort to be carried out by MSE, Inc. The purpose of this task is to develop and analyze designs for various cohesive ceramic fabrication (CCF) components. This quarter, the advanced molybdenum disicilide MHD electrode design was essentially completed. Final refinements will be made after molybdenum disilicide processing results are available and the final layer compositions are established. Work involving whisker incorporation was initiated on the high stress component. It is unlikely that whiskers will become low cost, so particulate reinforcement will be pursued. Modeling work will resume once a suitable aluminum oxide/silicon carbide composition is selected that can be fired to acceptable densities by pressureless sintering. Task 2, subcontracted to Applied Technology Laboratories (ATL), is principally directed at establishing a property data base for monolithic and laminated alumina fabricated using the CCF process. This quarter, ATL demonstrated that the CCF process does not compromise the flexure strength of alumina. Task 3, subcontracted to Ceramics Binder Systems, Inc., focused on CCF silicon carbide particulate reinforced alumina and on the development of processing procedures for nonoxide molybdenum disilicide. Preliminary results indicate that achieving high densities in silicon carbide particulate reinforced aluminum oxide will be difficult. Molybdenum disilicide results are encouraging, and it is clear that the CCF process will work with this nonoxide material. 3 refs., 18 figs., 4 tabs.

OXYGEN TRANSPORT CERAMIC MEMBRANES  

SciTech Connect

In the present quarter, the possibility of using a more complex interfacial engineering approach to the development of reliable and stable oxygen transport perovskite ceramic membranes/metal seals is discussed. Experiments are presented and ceramic/metal interactions are characterized. Crack growth and fracture toughness of the membrane in the reducing conditions are also discussed. Future work regarding this approach is proposed are evaluated for strength and fracture in oxygen gradient conditions. Oxygen gradients are created in tubular membranes by insulating the inner surface from the reducing environment by platinum foils. Fracture in these test conditions is observed to have a gradient in trans and inter-granular fracture as opposed to pure trans-granular fracture observed in homogeneous conditions. Fracture gradients are reasoned to be due to oxygen gradient set up in the membrane, variation in stoichiometry across the thickness and due to varying decomposition of the parent perovskite. The studies are useful in predicting fracture criterion in actual reactor conditions and in understanding the initial evolution of fracture processes.

Ceramic fiber reinforced filter  

DOE Patents (OSTI)

A filter for removing particulate matter from high temperature flowing fluids, and in particular gases, that is reinforced with ceramic fibers. The filter has a ceramic base fiber material in the form of a fabric, felt, paper of the like, with the refractory fibers thereof coated with a thin layer of a protective and bonding refractory applied by chemical vapor deposition techniques. This coating causes each fiber to be physically joined to adjoining fibers so as to prevent movement of the fibers during use and to increase the strength and toughness of the composite filter. Further, the coating can be selected to minimize any reactions between the constituents of the fluids and the fibers. A description is given of the formation of a composite filter using a felt preform of commercial silicon carbide fibers together with the coating of these fibers with pure silicon carbide. Filter efficiency approaching 100% has been demonstrated with these filters. The fiber base material is alternately made from aluminosilicate fibers, zirconia fibers and alumina fibers. Coating with Al.sub.2 O.sub.3 is also described. Advanced configurations for the composite filter are suggested.

Ceramics for fusion devices  

SciTech Connect

Ceramics are required for a number of applications in fusion devices, among the most critical of which are magnetic coil insulators, windows for RF heating systems, and structural uses. Radiation effects dominate consideration of candidate materials, although good pre-irradiation properties are a requisite. Materials and components can be optimized by careful control of chemical and microstructural content, and application of brittle material design and testing techniques. Future directions for research and development should include further extension of the data base in the areas of electrical, structural, and thermal properties; establishment of a fission neutron/fusion neutron correlation including transmutation gas effects; and development of new materials tailored to meet the specific needs of fusion reactors.

Process for producing advanced ceramics  

DOE Patents (OSTI)

A process for the synthesis of homogeneous advanced ceramics such as SiC+AlN, SiAlON, SiC+Al.sub.2 O.sub.3, and Si.sub.3 N.sub.4 +AlN from natural clays such as kaolin, halloysite and montmorillonite by an intercalation and heat treatment method. Included are the steps of refining clays, intercalating organic compounds into the layered structure of clays, drying the intercalated mixture, firing the treated atmospheres and grinding the loosely agglomerated structure. Advanced ceramics produced by this procedure have the advantages of homogeneity, cost effectiveness, simplicity of manufacture, ease of grind and a short process time. Advanced ceramics produced by this process can be used for refractory, wear part and structure ceramics.

Insulating Structural Ceramics Program, Final Report  

Science Conference Proceedings (OSTI)

New materials and corresponding manufacturing processes are likely candidates for diesel engine components as society and customers demand lower emission engines without sacrificing power and fuel efficiency. Strategies for improving thermal efficiency directly compete with methodologies for reducing emissions, and so the technical challenge becomes an optimization of controlling parameters to achieve both goals. Approaches being considered to increase overall thermal efficiency are to insulate certain diesel engine components in the combustion chamber, thereby increasing the brake mean effective pressure ratings (BMEP). Achieving higher BMEP rating by insulating the combustion chamber, in turn, requires advances in material technologies for engine components such as pistons, port liners, valves, and cylinder heads. A series of characterization tests were performed to establish the material properties of ceramic powder. Mechanical chacterizations were also obtained from the selected materials as a function of temperature utilizing ASTM standards: fast fracture strength, fatique resistance, corrosion resistance, thermal shock, and fracture toughness. All ceramic materials examined showed excellent wear properties and resistance to the corrosive diesel engine environments. The study concluded that the ceramics examined did not meet all of the cylinder head insert structural design requirements. Therefore we do not recommend at this time their use for this application. The potential for increased stresses and temperatures in the hot section of the diesel engine combined with the highly corrosive combustion products and residues has driven the need for expanded materials capability for hot section engine components. Corrosion and strength requirements necessitate the examination of more advanced high temperture alloys. Alloy developments and the understanding of processing, structure, and properties of supperalloy materials have been driven, in large part, by the gas turbine community over the last fifty years. Characterization of these high temperature materials has, consequently, concentrated heavily upon application conditions similiar to to that encountered in the turbine engine environment. Significantly less work has been performed on hot corrosion degradation of these materials in a diesel engine environment. This report examines both the current high temperature alloy capability and examines the capability of advanced nickle-based alloys and methods to improve production costs. Microstructures, mechanical properties, and the oxidation/corrosion behavior of commercially available silicon nitride ceramics were investigated for diesel engine valve train applications. Contact, sliding, and scratch damage mechanisms of commercially available silicon nitride ceramics were investigated as a function of microstructure. The silicon nitrides with a course microstructure showed a higher material removal rate that agrees with a higher wear volume in the sliding contact tests. The overall objective of this program is to develop catalyst materials systems for an advanced Lean-NOx aftertreatment system that will provide high NOx reduction with minimum engine fuel efficiency penalty. With Government regulations on diesel engine NOx emissions increasingly becoming more restrictive, engine manufacturers are finding it difficult to meet the regulations solely with engine design strategies (i.e. improved combustion, retarded timing, exhaust gas recirculation, etc.). Aftertreatment is the logical technical approach that will be necessary to achieve the required emission levels while at the same time minimally impacting the engine design and its associated reliability and durability concerns.

I captured it and now have it living in a large box. I have been feeding it commericial wild finch seed, niger seed and some sunflower seed. I have also provided a small cup of fine sand and a dish of water. Am I missing anything in it's diet? I had hoped to find someone to take it and care for it until it could fly again but have been unsuccessful so I may end up caring for it. It's wing is not visibly injured, however it can only flutter. I have been caring for it for 6 days now and it appears OK. Have also provided it with a small perch (branch) which it seems to use most of the time. Any other suggestions?

Ceramic tile expansion engine housing  

DOE Patents (OSTI)

An expandable ceramic tile housing for a high temperature engine is disclosed wherein each tile is independently supported in place in an interlocking matrix by retention mechanisms which mechanically couple the individual ceramic tiles to an outer metal support housing while maintaining thermal isolation of the metal housing from the ceramic tiles. The ceramic tiles are formed with either an octagonal front face portion and a square shank portion or a square front face portion with an octagonal shank portion. The length of the sides of the octagonal front face portion on one tile is equal to the length of the sides of the square front face portion of adjoining tiles to permit formation of an interlocking matrix. Fibrous ceramic sealing material may be placed between radial and tangential facing surfaces of adjacent tiles to limit radial gas flow there between. Labyrinth-sealed pressure-controlled compartments may be established between the tile housing and the outer metal support housing to control radial gas flow. 8 figures.

Ceramics for ATS industrial turbines  

DOE Green Energy (OSTI)

US DOE and most US manufacturers of stationary gas turbines are participating in a major national effort to develop advanced turbine systems (ATS). The ATS program will achieve ultrahigh efficiencies, environmental superiority, and cost competitiveness compared with current combustion turbine systems. A major factor in the improved efficiencies of simple cycle ATS gas turbines will be higher operating efficiencies than curren engines. These temperatures strain the limits of metallic alloy and flow-path cooling technologies. Ceramics materials offer a potential alterative to cooled turbine alloys for ATS turbines due to higher melting points than metallics. This paper evaluates ceramics technology and plant economic issues for ATS industrial turbine systems. A program with the objective of demonstrating first-stage ceramic vanes in a commerical industrial turbine is also described.

Oxygen Transport Ceramic Membranes  

Science Conference Proceedings (OSTI)

The present quarterly report describes some of the investigations on the structural properties of dense OTM bars provided by Praxair and studies on newer composition of Ti doped LSF. In the previous research, the reference point of oxygen occupancy was determined and verified. In the current research, the oxygen occupancy was investigated at 1200 C as a function of oxygen activity and compared with that at 1000 C. The cause of bumps at about 200 C was also investigated by using different heating and cooling rates during TGA. The fracture toughness of LSFT and dual phase membranes at room temperature is an important mechanical property. Vicker's indentation method was used to evaluate this toughness. Through this technique, a K{sub Ic} (Mode-I Fracture Toughness) value is attained by means of semi-empirical correlations between the indentation load and the length of the cracks emanating from the corresponding Vickers indentation impression. In the present investigation, crack propagation behavior was extensively analyzed in order to understand the strengthening mechanisms involved in the non-transforming La based ceramic composites. Cracks were generated using Vicker's indenter and used to identify and evaluate the toughening mechanisms involved. Preliminary results of an electron microscopy study of the origin of the slow kinetics on reduction of ferrites have been obtained. The slow kinetics appear to be related to a non-equilibrium reduction pathway that initially results in the formation of iron particles. At long times, equilibrium can be reestablished with recovery of the perovskite phase. Modeling of the isotopic transients on operating membranes (LSCrF-2828 at 900 C) and a ''frozen'' isotope profile have been analyzed in conjunction with a 1-D model to reveal the gradient in oxygen diffusivity through the membrane under conditions of high chemical gradients.

Method for joining ceramic shapes  

DOE Patents (OSTI)

A method for joining shapes of ceramic materials together to form a unitary ceramic structure. In the method of the invention, a mixture of two or more chemical components which will react exothermically is placed between the surfaces to be joined, and the joined shapes heated to a temperature sufficient to initiate the exothermic reaction forming a joining material which acts to bond the shapes together. Reaction materials are chosen which will react exothermically at temperatures below the degradation temperature of the materials to be joined. The process is particularly suited for joining composite materials of the silicon carbide-silicon carbide fiber type.

Ceramics in fission and fusion technology  

SciTech Connect

The role of ceramic components in fission and fusion reactors is described. Almost all of the functions normally performed by ceramics, except mechanical, are required of nuclear ceramics. The oxides of uranium and plutonium are of predominant importance in nuclear applications, but a number of other ceramics play peripheral roles. The unique service conditions under which nuclear ceramics must operate include intense radiation fields, high temperatures and large temperature gradients, and aggressive chemical environments. Examples of laboratory research designed to broaden understanding of the behavior of uranium dioxide in such conditions are given. The programs described include high temperature vaporization, diffusional processes, and interaction with hydrogen.

Ceramic heat exchangers: manufacturing techniques and performance  

SciTech Connect

The objective of the ceramic heat pipe program being conducted at Los Alamos is demonstration of the practical feasibility of this technology for the solution of severe high temperature recuperation functions. Ceramic heat pipe recuperators have been theoretically shown to offer distinct advantages over conventional ceramic heat exchangers from the standpoint of efficiency of heat recuperation and economics. The main stumbling block to their widespread utilization is related to the problems of materials for construction and the details of fabrication and assembly. The performance objectives of ceramic heat pipes and some aspects of the materials technology program aimed at solving the problem of economic ceramic heat pipe fabrication are described.

Gas Separations using Ceramic Membranes  

DOE Green Energy (OSTI)

This project has been oriented toward the development of a commercially viable ceramic membrane for high temperature gas separations. A technically and commercially viable high temperature gas separation membrane and process has been developed under this project. The lab and field tests have demonstrated the operational stability, both performance and material, of the gas separation thin film, deposited upon the ceramic membrane developed. This performance reliability is built upon the ceramic membrane developed under this project as a substrate for elevated temperature operation. A comprehensive product development approach has been taken to produce an economically viable ceramic substrate, gas selective thin film and the module required to house the innovative membranes for the elevated temperature operation. Field tests have been performed to demonstrate the technical and commercial viability for (i) energy and water recovery from boiler flue gases, and (ii) hydrogen recovery from refinery waste streams using the membrane/module product developed under this project. Active commercializations effort teaming with key industrial OEMs and end users is currently underway for these applications. In addition, the gas separation membrane developed under this project has demonstrated its economical viability for the CO2 removal from subquality natural gas and landfill gas, although performance stability at the elevated temperature remains to be confirmed in the field.

Performance of ceramic membrane filters  

SciTech Connect

CeraMem Corp.`s ceramic-membrane coated, dead-end ceramic filters offer a promising alternative to ceramic candle filters providing long-term operational and reliability issues are resolved: regenerability of filter passages by back pulse cleaning, tolerance to alkali-containing combustion gas and thermal/chemical aging. ANL is responsible for analytical modeling of filtration and pulse cleaning operations, flow-through testing, and prediction of filter response to thermal cycling under realistic service conditions. A test apparatus was built to expose ceramic filter specimens to chemical environments simulating operation of pressurized fluidized bed and integrated gasification combined cycle plants. Four long-duration tests have been conducted in which 100-cpsi channel filters were exposed to ash collected downstream of the cyclone separator at the PFBC plant at Tidd. Results are discussed. Focus has now shifted to exposing the advanced candle filter specimens to reducing gas environments containing NaCl, H{sub 2}S, H{sub 2}O, and gasification ash.

CHAPMAN*, GERALD R. DICKENS**, BRANDON DUGAN**, and GEORGE J. HIRASAKI* † ABSTRACT. Gas hydrates dominated by methane naturally occur in deep marine sediment along continental margins. These compounds form in pore space between the seafloor and a sub-bottom depth where appropriate stability conditions prevail. However, the amount and distribution of gas hydrate within this zone, and free gas below, can vary significantly at different locations. To understand this variability, we develop a one-dimensional numerical model that simulates the accumulation of gas hydrates in marine sediments due to upward and downward fluxes of methane over time. The model contains rigorous

Catalyzed Ceramic Burner Material  

SciTech Connect

Catalyzed combustion offers the advantages of increased fuel efficiency, decreased emissions (both NOx and CO), and an expanded operating range. These performance improvements are related to the ability of the catalyst to stabilize a flame at or within the burner media and to combust fuel at much lower temperatures. This technology has a diverse set of applications in industrial and commercial heating, including boilers for the paper, food and chemical industries. However, wide spread adoption of catalyzed combustion has been limited by the high cost of precious metals needed for the catalyst materials. The primary objective of this project was the development of an innovative catalyzed burner media for commercial and small industrial boiler applications that drastically reduce the unit cost of the catalyzed media without sacrificing the benefits associated with catalyzed combustion. The scope of this program was to identify both the optimum substrate material as well as the best performing catalyst construction to meet or exceed industry standards for durability, cost, energy efficiency, and emissions. It was anticipated that commercial implementation of this technology would result in significant energy savings and reduced emissions. Based on demonstrated achievements, there is a potential to reduce NOx emissions by 40,000 TPY and natural gas consumption by 8.9 TBtu in industries that heavily utilize natural gas for process heating. These industries include food manufacturing, polymer processing, and pulp and paper manufacturing. Initial evaluation of commercial solutions and upcoming EPA regulations suggests that small to midsized boilers in industrial and commercial markets could possibly see the greatest benefit from this technology. While out of scope for the current program, an extension of this technology could also be applied to catalytic oxidation for volatile organic compounds (VOCs). Considerable progress has been made over the course of the grant period in accomplishing these objectives. Our work in the area of Pd-based, methane oxidation catalysts has led to the development of highly active catalysts with relatively low loadings of Pd metal using proprietary coating methods. The thermal stability of these Pd-based catalysts were characterized using SEM and BET analyses, further demonstrating that certain catalyst supports offer enhanced stability toward both PdO decomposition and/or thermal sintering/growth of Pd particles. When applied to commercially available fiber mesh substrates (both metallic and ceramic) and tested in an open-air burner, these catalyst-support chemistries showed modest improvements in the NOx emissions and radiant output compared to uncatalyzed substrates. More significant, though, was the performance of the catalyst-support chemistries on novel media substrates. These substrates were developed to overcome the limitations that are present with commercially available substrate designs and increase the gas-catalyst contact time. When catalyzed, these substrates demonstrated a 65-75% reduction in NOx emissions across the firing range when tested in an open air burner. In testing in a residential boiler, this translated into NOx emissions of <15 ppm over the 15-150 kBtu/hr firing range.

Ceramic Technology for Advanced Heat Engines Project  

DOE Green Energy (OSTI)

The Ceramic Technology For Advanced Heat Engines Project was developed by the Department of Energy's Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS's Advanced Materials Development Program, was developed to meet the ceramic technology requirements of the OTS's automotive technology programs. Significant accomplishments in fabricating ceramic components for the Department of Energy (DOE), National Aeronautics and Space Administration (NASA), and Department of Defense (DOD) advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. However, these programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. An assessment of needs was completed, and a five year project plan was developed with extensive input from private industry. The objective of the project is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on structural ceramics for advanced gas turbine and diesel engines, ceramic hearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines.

Leonard Wood and the American Empire  

E-Print Network (OSTI)

During the ten years following the Spanish American War (1898 to 1908), Major General Leonard Wood served as the primary agent of American imperialism. Wood was not only a proconsul of the new American Empire; he was a symbol of the empire and the age in which he served. He had the distinction of directing civil and military government in Cuba and the Philippines where he implemented the imperial policies given to him by the administrations of William McKinley and Theodore Roosevelt. In Cuba, he labored to rebuild a state and a civil society crippled by decades of revolutionary ferment and guided the administration's policy through the dangerous channels of Cuban politics in a way that satisfied at least to the point of avoiding another revolution both the Cubans and the United States. In the Philippines, Wood took control of the Moro Province and attempted to smash the tribal-religious leadership of Moro society in order to bring it under direct American rule. His personal ideology, the imperial policies he shepherded, and the guidance he provided to fellow military officers and the administrations he served in matters of colonial administration and defense shaped the American Empire and endowed it with his personal stamp.

The organic support may also include an inorganic metal portion that remains on destruction of the organic portion, providing structural support and/or chemical reactivity to the membrane. The channels formed when the organic support is destroyed provide the ability to withdraw small catalytic products or size-separated molecules from the metal oxide membrane. In addition, the channel-containing membranes retain all of the advantages of existing porous ceramic membranes.

Great American Smokeout  

E-Print Network (OSTI)

by the American Cancer Society, is an annual event that encourages smokers to quit for at least 1 day in the hope that this might challenge them to stop permanently (1). This year, GASO will be held on November 18. Major changes have occurred since the first GASO in 1977. In 1978, approximately 34 % of adults smoked; by 2009, nearly 21 % smoked (24). Federal laws now prohibit smoking on airlines, and 24 states and the District of Columbia have comprehensive smoking bans (3,4). The U.S. government also has added coverage of smoking cessation treatments to health plans. As of October 1, 2010, Medicaid programs are required to cover tobaccodependence treatments for pregnant women, and in 2011, cessation coverage will be provided to all federal employees, retirees, and their spouses and dependents. Despite progress, 46.6 million U.S. adults smoke, 40% of nonsmokers are exposed to secondhand smoke, and 443,000 deaths each year are attributed to smoking and secondhand smoke (35). Additional information and support for quitting is available online

Dynamic testing and characterization of pre-fractured ceramic  

SciTech Connect

Nearly all of the mechanical behavior studies of armor ceramics, to date, havc involved the characterization and testing of pristine ceramic material. However, balhstic impact causes a strong shock front to propagate rapidly through the ceramic before much penetration can occur. A strong shock wave can result in localized compressive failure and fragmentation of the ceramic before its amplitude is amnuated below the compressive strength of the ceramic. Goals of this effort were to creatc shock-fractured ceramic using test assemblies which maintain the intergranular coupling and high density of the ceramic, characterize the extent and homogeneity of the fragmentation and dilatation of the ceramic, and test the compressive dynamic behavior of the shock-fractured ceramic under conditions of confining pressure. This effort will provide data to support models of the penetration resistance of fractured ceramics including degraded moduli, failure strength-strain, and post-failure characterization of the erosive properties of comminuted ceramic and penetratot materials.

Ceramic vane demonstration in an industrial turbine  

SciTech Connect

A DOE program with Allison Engine Co. will demonstrate ceramic vanes in an industrial turbine. First-stage ceramic vanes and metallic mounts are to be designed, fabricated, and operated in a short-term engine test (up to 50 hr). The vanes and mounts will then be retrofitted into an existing turbine for operation at a commercial site for up to 8000 hr. They have been designed. Thermal and stress analyses of the vanes have calculated acceptable fast fracture stress levels and probabilities of survival > 99.99% for turbine continuous power and emergency shutdown (thermal shock) conditions. Max calculated steady-state stress is 169 MPa at 1182 C, so currently available ceramics appear to provide acceptable fast fracture strengths for use in industrial turbines. Long-term materials test will evaluate the lifetimes and retained strength of ceramics at stress and temperature levels in the range calculated from the ceramic vane analyses. Results of these tests will support on which vane material will be used in the long duration turbine demonstration. A successful demonstration could provide a basis for incorporating first-stage ceramic vanes into current generation industrial turbines and also the introduction of ceramic airfoils into downstream rows of future high temperature Advanced Turbine System (ATS) engines.

Ceramic technology for advanced heat engines  

DOE Green Energy (OSTI)

The Ceramic Technology Project was initiated in 1983 for the purpose of developing highly reliable structural ceramics for applications in advanced heat engines, such as automotive gas turbines and advanced heavy duty diesel engines. The reliability problem was determined to be a result of uncontrolled populations of processing flaws in the brittle, flaw-sensitive materials, along with microstructural features, such as grain boundary phases, that contribute to time dependent strength reduction in service at high temperatures. The approaches taken to develop high reliability ceramics included the development of tougher materials with greater tolerance to microstructural flaws, the development of advanced processing technology to minimize the size and number of flaws, and the development of mechanical testing methodology and the characterization of time dependent mechanical behavior, leading to a life prediction methodology for structural ceramics. The reliability goals of the program were largely met by 1993, but commercial implementation of ceramic engine components has been delayed by the high cost of the components. A new effort in Cost Effective Ceramics for Heat Engines was initiated in 1993 and is expected to develop the manufacturing technology leading to an order of magnitude cost reduction. The program has been planned for a five year period.

American racism and African diplomats: race and American Cold War policy in West Africa  

E-Print Network (OSTI)

Two of the most significant influences on post-World War II American society were Cold War ideology and the struggle over civil rights. The Kennedy years provide a special opportunity to examine the relationship between these two facets of modern American society. The interconnectedness between Cold War ideology and civil rights increased during the 1960s. Cold War tensions escalated and the American government became increasingly concerned about the effect of racial strife on the country's image abroad. Many officials feared that America's racial problems placed her in a weaker position than the Soviet Union in the struggle to win the "hearts and minds" of Latin America, Asia, and Africa. This study will examine the political and social ramifications of the experiences of African diplomats in the United States during the Kennedy administration within both a national and international context. African encounters with American racism illustrate the interplay between foreign policy and domestic pressures and the globalization of the civil rights movement. The Kennedy administration, especially the State Department, took decisive action on the behalf of the African diplomats. However, racial problems confronting the African diplomats could not be resolved without resolving the racial problems confronting black Americans and other people of color in the United States. The main argument of this thesis is that the administration's efforts to solve this international image problem were significant steps towards the eventual end of de jure segregation in the long-term. This thesis includes an examination of relations between the United States and British West Africa, the African and Soviet response to American racism, the efforts of the State Department on behalf of the mistreated African diplomats, and the relationship between the civil rights movement and independence movements in Africa.

Ceramic turbine stator vane and shroud support  

SciTech Connect

A support system for supporting the stationary ceramic vanes and ceramic outer shrouds which define the motive fluid gas path in a gas turbine engine is shown. Each individual segment of the ceramic component whether a vane or shroud segment has an integral radially outwardly projecting stem portion. The stem is enclosed in a split collet member of a high-temperature alloy material having a cavity configured to interlock with the stem portion. The generally cylindrical external surface of the collet engages a mating internal cylindrical surface of an aperture through a supporting arcuate ring segment with mating camming surfaces on the two facing cylindrical surfaces such that radially outward movement of the collet relative to the ring causes the internal cavity of the collet to be reduced in diameter to tightly engage the ceramic stem disposed therein. A portion of the collet extends outwardly through the ring segment opposite the ceramic piece and is threaded for receiving a nut and a compression washer for retaining the collet in the ring segment under a continuous biasing force urging the collet radially outwardly.

Proton conducting ceramic membranes for hydrogen separation  

Science Conference Proceedings (OSTI)

A multi-phase proton conducting material comprising a proton-conducting ceramic phase and a stabilizing ceramic phase. Under the presence of a partial pressure gradient of hydrogen across the membrane or under the influence of an electrical potential, a membrane fabricated with this material selectively transports hydrogen ions through the proton conducting phase, which results in ultrahigh purity hydrogen permeation through the membrane. The stabilizing ceramic phase may be substantially structurally and chemically identical to at least one product of a reaction between the proton conducting phase and at least one expected gas under operating conditions of a membrane fabricated using the material. In a barium cerate-based proton conducting membrane, one stabilizing phase is ceria.

Enabling Technologies for Ceramic Hot Section Components  

SciTech Connect

Silicon-based ceramics are attractive materials for use in gas turbine engine hot sections due to their high temperature mechanical and physical properties as well as lower density than metals. The advantages of utilizing ceramic hot section components include weight reduction, and improved efficiency as well as enhanced power output and lower emissions as a result of reducing or eliminating cooling. Potential gas turbine ceramic components for industrial, commercial and/or military high temperature turbine applications include combustor liners, vanes, rotors, and shrouds. These components require materials that can withstand high temperatures and pressures for long duration under steam-rich environments. For Navy applications, ceramic hot section components have the potential to increase the operation range. The amount of weight reduced by utilizing a lighter gas turbine can be used to increase fuel storage capacity while a more efficient gas turbine consumes less fuel. Both improvements enable a longer operation range for Navy ships and aircraft. Ceramic hot section components will also be beneficial to the Navy's Growth Joint Strike Fighter (JSF) and VAATE (Versatile Affordable Advanced Turbine Engines) initiatives in terms of reduced weight, cooling air savings, and capability/cost index (CCI). For DOE applications, ceramic hot section components provide an avenue to achieve low emissions while improving efficiency. Combustors made of ceramic material can withstand higher wall temperatures and require less cooling air. Ability of the ceramics to withstand high temperatures enables novel combustor designs that have reduced NO{sub x}, smoke and CO levels. In the turbine section, ceramic vanes and blades do not require sophisticated cooling schemes currently used for metal components. The saved cooling air could be used to further improve efficiency and power output. The objectives of this contract were to develop technologies critical for ceramic hot section components for gas turbine engines. Significant technical progress has been made towards maturation of the EBC and CMC technologies for incorporation into gas turbine engine hot-section. Promising EBC candidates for longer life and/or higher temperature applications relative to current state of the art BSAS-based EBCs have been identified. These next generation coating systems have been scaled-up from coupons to components and are currently being field tested in Solar Centaur 50S engine. CMC combustor liners were designed, fabricated and tested in a FT8 sector rig to demonstrate the benefits of a high temperature material system. Pretest predictions made through the use of perfectly stirred reactor models showed a 2-3x benefit in CO emissions for CMC versus metallic liners. The sector-rig test validated the pretest predictions with >2x benefit in CO at the same NOx levels at various load conditions. The CMC liners also survived several trip shut downs thereby validating the CMC design methodology. Significant technical progress has been made towards incorporation of ceramic matrix composites (CMC) and environmental barrier coatings (EBC) technologies into gas turbine engine hot-section. The second phase of the program focused on the demonstration of a reverse flow annular CMC combustor. This has included overcoming the challenges of design and fabrication of CMCs into 'complex' shapes; developing processing to apply EBCs to 'engine hardware'; testing of an advanced combustor enabled by CMCs in a PW206 rig; and the validation of performance benefits against a metal baseline. The rig test validated many of the pretest predictions with a 40-50% reduction in pattern factor compared to the baseline and reductions in NOx levels at maximum power conditions. The next steps are to develop an understanding of the life limiting mechanisms in EBC and CMC materials, developing a design system for EBC coated CMCs and durability testing in an engine environment.

Cost-effective ceramics program in the United States  

DOE Green Energy (OSTI)

The 5-year Cost-Effective Ceramics for Heat Engines program began in 1993. This effort reflects the realization that the problems with reliability of structural ceramics have been largely overcome, but the high cost of structural ceramics is limited their use in commercial applications. The technical causes of high cost were identified, and a technical plan developed. The work elements in the program include the following: economic cost modeling, ceramic machining, powder synthesis, alternative forming and densification processes, yield improvement, standards development, and low-expansion ceramics.

Support Services for Ceramic Fiber-Ceramic Matrix Composites  

DOE Green Energy (OSTI)

Structural and functional materials used in solid- and liquid-fueled energy systems are subject to gas- and condensed-phase corrosion and erosion by entrained particles. For a given material, its temperature and the composition of the corrodents determine the corrosion rates, while gas flow conditions and particle aerodynamic diameters determine erosion rates. Because there are several mechanisms by which corrodents deposit on a surface, the corrodent composition depends not only on the composition of the fuel, but also on the temperature of the material and the size range of the particles being deposited. In general, it is difficult to simulate under controlled laboratory conditions all of the possible corrosion and erosion mechanisms to which a material may be exposed in an energy system. Therefore, with funding from the Advanced Research Materials Program, the University of North Dakota Energy & Environmental Research Center (EERC) is coordinating with NCC Engineering and the National Energy Technology Laboratory (NETL) to provide researchers with no-cost opportunities to expose materials in pilot-scale systems to conditions of corrosion and erosion similar to those occurring in commercial power systems. The EERC has two pilot-scale solid-fuel systems available for exposure of materials coupons. The slagging furnace system (SFS) was built under the DOE Combustion 2000 Program as a testing facility for advanced heat exchanger subsystems. It is a 2.5-MMBtu/hr (2.6 x 10{sup 6} kJ/hr) solid-fuel combustion system with exit temperatures of 2700 to 2900 F to ensure that the ash in the main combustor is molten and flowing. Sample coupons may be exposed in the system either within the slagging zone or near the convective air heater at 1800 F (980 C). In addition, a pilot-scale entrained-bed gasifier system known as the transport reactor development unit (TRDU) is available. Also operating at approximately 2.5 MMBtu/hr (2.6 x 10{sup 6} kJ/hr), it is a pressurized unit built to simulate the Kellogg entrained-bed gasifier in use at the Southern Company Services Wilsonville facility, but at 1/10 of the firing rate. At the exit of the unit is a large candle filter vessel typically operated at approximately 1000 F (540 C) in which coupons of materials can be inserted to test their resistance to gasifier ash and gas corrosion. The system also has ports for testing of hydrogen separation membranes that are suitably contained in a pressure housing. In addition, NETL is operating the combustion and environmental research facility (CERF). In recent years, the 0.5 MMBtu/hr (0.5 x 10{sup 6} kJ/hr) CERF has served as a host for exposure of over 60 ceramic and alloy samples at ambient pressure as well as at 200 psig (for tubes). Samples have been inserted in five locations covering 1700-2600 F (930-1430 C), with exposures exceeding 1000 hours. In the present program, the higher priority metals are to be tested at 1500-1600 F (820-870 C) in one CERF location and near 1800-2000 F (980-1090 C) at other locations to compare results with those from the EERC tests.

Novel, Ceramic Membrane System For Hydrogen Separation  

Science Conference Proceedings (OSTI)

Separation of hydrogen from coal gas represents one of the most promising ways to produce alternative sources of fuel. Ceramatec, teamed with CoorsTek and Sandia National Laboratories has developed materials technology for a pressure driven, high temperature proton-electron mixed conducting membrane system to remove hydrogen from the syngas. This system separates high purity hydrogen and isolates high pressure CO{sub 2} as the retentate, which is amenable to low cost capture and transport to storage sites. The team demonstrated a highly efficient, pressure-driven hydrogen separation membrane to generate high purity hydrogen from syngas using a novel ceramic-ceramic composite membrane. Recognizing the benefits and limitations of present membrane systems, the all-ceramic system has been developed to address the key technical challenges related to materials performance under actual operating conditions, while retaining the advantages of thermal and process compatibility offered by the ceramic membranes. The feasibility of the concept has already been demonstrated at Ceramatec. This project developed advanced materials composition for potential integration with water gas shift rectors to maximize the hydrogenproduction.

Cordierite Glass-Ceramics for Dielectric Materials  

Science Conference Proceedings (OSTI)

The objective of this project is to examine the potential of using Malaysian silica sand deposit as SiO2 raw material in producing cordierite glass-ceramics (2MgO-2Al2O3-5SiO2) for dielectric materials. Upgraded silica sands from Terengganu and ex-mining land in Perak were used in the test-works. The glass batch of the present work has a composition of 45.00% SiO2, 24.00% Al2O3, 15.00% MgO and 8.50% TiO2 as nucleation agent. From the differential thermal analysis results, the crystallization temperature was found to start around 900 deg. C. The glass samples were heat-treated at 900 deg. C and 1000 deg. C. The X-ray diffraction analysis (XRD) results showed glass-ceramics from Terengganu samples containing mainly cordierite and minor {beta}-quartz crystals. However, glass-ceramics from ex-mining land samples contained mainly {alpha}-quartz and minor cordierite crystals. Glass-ceramics with different crystal phases exhibit different mechanical, dielectric and thermal properties. Based on the test works, both silica sand deposits, can be potentially used to produce dielectric material component.

Development and Performance Testing of a New Ceramic Recuperator  

E-Print Network (OSTI)

Metal heat exchangers have been used in industrial heat recovery applications for many years. Ceramic heat exchangers are relatively new, but are gaining acceptance as more field experience becomes available. The advantage of the ceramic units over metal units is the higher temperature capabilities of the ceramic which eliminate the need for costly over-temperature controls and dilution air systems. The problems encountered with ceramic heat exchangers to date have been variable leakage and lack of durability. These problems are associated with the high thermal stresses in the compact designs and with the seals required to connect the ceramic to the metal ductwork. Coors Porcelain Company has been engaged in the development of ceramic heat exchangers for heat engine and industrial applications for several years. Durability problems were encountered from thermal stresses in these applications with recuperators made from conventional ceramics. This resulted in development' of a new ceramic mixed oxide material specifically for heat exchangers. Changes in geometry of the ceramic matrices were also made to further reduce the stresses in order to increase product durability. A housing was designed and a ceramic gasket was selected to minimize the chances of significant leakage from the seal area of the recuperator. The performance of different recuperator designs and the durability results attained to date will be presented as well as results on field testing.

CRYSTALLINE CERAMIC WASTE FORMS: REFERENCE FORMULATION REPORT  

Science Conference Proceedings (OSTI)

The research conducted in this work package is aimed at taking advantage of the long term thermodynamic stability of crystalline ceramics to create more durable waste forms (as compared to high level waste glass) in order to reduce the reliance on engineered and natural barrier systems. Durable ceramic waste forms that incorporate a wide range of radionuclides have the potential to broaden the available disposal options and to lower the storage and disposal costs associated with advanced fuel cycles. Assemblages of several titanate phases have been successfully demonstrated to incorporate radioactive waste elements, and the multiphase nature of these materials allows them to accommodate variation in the waste composition. Recent work has shown that they can be successfully produced from a melting and crystallization process. The objective of this report is to explain the design of ceramic host systems culminating in a reference ceramic formulation for use in subsequent studies on process optimization and melt property data assessment in support of FY13 melter demonstration testing. The waste stream used as the basis for the development and testing is a combination of the projected Cs/Sr separated stream, the Trivalent Actinide - Lanthanide Separation by Phosphorous reagent Extraction from Aqueous Komplexes (TALSPEAK) waste stream consisting of lanthanide fission products, the transition metal fission product waste stream resulting from the transuranic extraction (TRUEX) process, and a high molybdenum concentration with relatively low noble metal concentrations. In addition to the combined CS/LN/TM High Mo waste stream, variants without Mo and without Mo and Zr were also evaluated. Based on the results of fabricating and characterizing several simulated ceramic waste forms, two reference ceramic waste form compositions are recommended in this report. The first composition targets the CS/LN/TM combined waste stream with and without Mo. The second composition targets with CS/LN/TM combined waste stream with Mo and Zr removed. Waste streams that contain Mo must be produced in reducing environments to avoid Cs-Mo oxide phase formation. Waste streams without Mo have the ability to be melt processed in air. A path forward for further optimizing the processing steps needed to form the targeted phase assemblages is outlined in this report. Processing modifications including melting in a reducing atmosphere, and controlled heat treatment schedules are anticipated to improve the targeted elemental partitioning.

A Ceramic membrane to Recycle Caustic  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

A A Ceramic Membrane to Recycle Caustic in Low-Activity Waste Stream Processing The Office of Waste Processing is sponsoring an R&D project with Ceramatec, Inc. to develop a ceramic membrane capable of separating sodium from the Hanford Low Activity Waste (LAW) stream. The Hanford High-Level Waste (HLW) tanks must be maintained in a caustic environment to inhibit corrosion. Consequently, they contain large quantities of NaOH. Ultimately the HLW will be retrieved, separated into HLW and LAW streams, with both streams being vitrified at the Waste Treatment Plant (WTP). Prior to processing, additional NaOH will be added to the LAW stream to solubilize the alumina, preventing alumina precipitation, but further increasing the NaOH quantity. This project's goal is to separate the sodium from the LAW stream prior to vitrification which will allow the NaOH to be recycled and further

Ceramic component manufacturing process development. Final report  

SciTech Connect

Ceramic materials are well suited for applications where temperature, wear, and corrosion resistance are necessary. The toughness and wear resistance properties that make ceramics desirable, also make fabrication of parts difficult. The objective of this CRADA was to increase the grinding efficiency on Ceradyne Incorporated silicon nitride. This was to be accomplished through optimization of grinding wheel life and increasing silicon nitride material removal rates. Experiments were conducted to determine the relationship between grinding parameters, wheel wear, and material removal rates. Due to excessive, unexplained variation in the experimental results, a consistent relationship between the selected grinding parameters and wheel wear could not be established. Maximum material removal rates were limited by spindle and table drive power. Additional experiments were conducted to evaluate high speed grinding. When compared to conventional grinding speeds, the material removal rates using high speed grinding (13,000 SFM) increased by a factor of five to ten with no degradation of fracture strength.

Ceramic Cross Flow Recuperator Design Parameters  

E-Print Network (OSTI)

GTE Products Corporation has developed a compact ceramic cross flow recuperator for high temperature industrial heat recovery applications. They recently completed a jointly funded project with the DOE, (Contract #EX-76-C-0 1-2162) to demonstrate the performance of the ceramic recuperator in various industrial furnaces. The ceramic cross flow recuperator core has multiple rectangular flow passages (perpendicular to each other) for the air and gas. Various flow passages are available contingent upon requirements of the particular application. In selecting and sizing a matrix for a given application, one may design a recuperator on the basis of a minimum for one or more of the following parameters; frontal area, length, volume, weight, pressure drop and cost. This paper discusses how the designer can select an optimum design from the various heat exchanger surfaces available and then predict the performance of a recuperator in any given application. The results of wind tunnel tests utilizing a single blow technique, determining a heat transfer parameter, the Colburn factor (j), and a flow friction parameter, Fanning Friction factor (f) are presented and discussed. Methods that illustrate how the (j) and (f) data can be used to compare the relative merits of two or more heat exchanger surface are presented. A typical furnace recuperation example is presented and calculations are detailed to illustrate the design procedures.

Ceramic breeder materials : status and needs.  

DOE Green Energy (OSTI)

The tritium breeding blanket is one of the most important components of a fusion reactor because it directly involves both energy extraction and tritium production, both of which are critical to fusion power. Because of their overall desirable properties, lithium-containing ceramic solids are recognized as attractive tritium breeding materials for fusion reactor blankets. Indeed, their inherent thermal stability and chemical inertness are significant safety advantages. In numerous in-pile experiments, these materials have performed well, showing good thermal stability and good tritium release characteristics. Tritium release is particularly facile when an argon or helium purge gas containing hydrogen, typically at levels of about 0.1%, is used. However, the addition of hydrogen to the purge gas imposes a penalty when it comes to recovery of the tritium produced in the blanket. In particular, a large amount of hydrogen in the purge gas will necessitate a large multiple-stage tritium purification unit, which could translate into higher costs. Optimizing tritium release while minimizing the amount of hydrogen necessary in the purge gas requires a deeper understanding of the tritium release process, especially the interactions of hydrogen with the surface of the lithium ceramic. This paper reviews the status of ceramic breeder research and highlights several issues and data needs.

Corrosion resistant refractory ceramics for slagging gasifier environment  

Science Conference Proceedings (OSTI)

Integrated gasification combined cycle power systems are the most efficient and economical power generation systems with a relatively low environmental impact. The gasification process requires the optimal design of gasifiers with extremely corrosion resistant refractory lining. The majority of the refractory materials tested for gasifier lining applications cannot resist the action of slagging corrosive environment combined with high operation temperatures as high as 1600?C and possible thermal shocks and thermal expansion mismatch between the lining and the slag. Silicon carbide-based ceramics and some zirconia- and zircon-based ceramics manufactured by Ceramic Protection Corporation (CPC) have been tested in a simulated coal-fired slagging gasifier environment at a temperature of 1500?C. Crucible ceramic samples have been examined after exposure to the slag at high temperature. Microstructure studies of the ceramic zone contacted with the slag have been carried out. The highest performance, i.e. the absence of corrosion damage and thermal cracking after testing, was observed for silicon carbide-based ceramics ABSC formed by silicon carbide grains with an optimized particle size distribution bonded by the aluminosilicate crystalline-glassy matrix. Dense zirconia and alumina-zirconia and slightly porous zircon ceramics demonstrated comparatively lower performance due to their lower corrosion resistance and greater thermal cracking. ABSC ceramics can be manufactured as thick-walled large components and may be considered as a promising material for gasifier refractory applications. Similar ceramics, but with finer grain sizes, may also be recommended for thermocouple protection.

Support services for Ceramic Fiber-Ceramic Matrix Composites. Annual technical progress report  

SciTech Connect

Higher working-fluid temperatures are required to boost efficiency, exposing subsystems to more corrosive environments. Issues of special concern to ceramists are corrosion and blinding of hot-gas particulate filters and catastrophic failure of high-temperature ceramic heat exchangers. Fuel and operational factors that affect the corrosion rates of structural ceramics in coal-fired combustor systems are described, with examples of the corrosion of silicon carbide-based materials. Attention is focused on hot-gas particulate filtration and heat exchangers; gasification systems are also discussed. Objective of the report is to help the experimentalist measuring these factors to better design tests.

Ceramic Technology Project. Semiannual progress report, April 1991--September 1991  

DOE Green Energy (OSTI)

The Ceramic Technology Project was developed by the USDOE Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS`s Materials Development Program, was developed to meet the ceramic technology requirements of the OTS`s automotive technology programs. Significant accomplishments in fabricating ceramic components for the USDOE and NASA advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. A five-year project plan was developed with extensive input from private industry. In July 1990 the original plan was updated through the estimated completion of development in 1993. The objective is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on the structural ceramics for advanced gas turbine and diesel engines, ceramic bearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities.

Evaluation of Sialon internal combustion engine components and fabrication of several ceramic components for automotive applications  

DOE Green Energy (OSTI)

Fabrication development work was carried out on a push-rod tip having a stepped OD design and a 90[degree] shoulder in the transition area. Spray-dried Sialon premix was used in dry press tooling, and components were densified to about 98% of theoretical density using pressureless sintering conditions. Upon evaluation of the sintered components, it was found that afl components showed defects in the transition area. Modifications of the pressing parameters, incorporation of a 45[degree] angle in the shoulder area, and the use of tailored premix did not lead to the fabrication of defect-free parts. From these observations, it was concluded that the original part design could not easily be adapted to high-volume ceramic manufacturing methods. Subsequently, a modification to the desip was implemented. An SiC material with improved toughness (Hexoloy SX) was used for fabricating several test components with a closely machined, straight OD design. Pressureless-sintered and post-hot isostatically pressed (HIPed) Hexoloy SX components were supplied to The American Ceramic Engine Company (ACE) for assembly and testing. Fuel pump push-rod assemblies with Hemoloy SX tips were prepared by ACE, but no testing has been carried out to date.

Ceramic turbine components research and development. Part 1. Ceramic rotor-blade development. Final report  

SciTech Connect

The principal objective of this program was to develop (through design, analysis and laboratory spin testing) the design techniques for uncooled ceramic rotor blades. Present-day materials, fabrication techniques and system operating conditions were assumed in the program. The unique compound curvature dovetail attachment concept was generated and two configurations of this concept were generated for detailed study. In addition a three-piece blade assembly consisting of ceramic blade/superalloy intermediate piece/metal disk was conceived. An additional important design feature was the use of a compliant layer pad between ceramic and metal contact surfaces. Silicon nitride root forms of two preliminary root designs with flat surface dovetails and of the two configurations with compound curvature dovetails were manufactured and spin tested to failure with very encouraging results. A statistical assessment of failures was conducted by combining results from finite element stress analysis and the statistical mechanical properties of Norton NC 132 silicon nitride. This provided a failure prediction method that correlated well with the spin test results. The significant influence of surface finish that translates to surface flaw severity and orientation was dramatically illustrated in this study and points to the need for improved methods of manufacturing ceramic components for gas turbine application.

Sulfide ceramics in molten-salt electrolyte batteries  

DOE Green Energy (OSTI)

Sulfide ceramics are finding application in the manufacture of advanced batteries with molten salt electrolyte. Use of these ceramics as a peripheral seal component has permitted development of bipolar Li/FeS{sub 2} batteries. This bipolar battery has a molten lithium halide electrolyte and operates at 400 to 450C. Initial development and physical properties evaluations indicate the ability to form metal/ceramic bonded seal (13-cm ID) components for use in high-temperature corrosive environments. These sealants are generally CaAl{sub 2}S{sub 4}-based ceramics. Structural ceramics (composites with oxide or nitride fillers), highly wetting sealant formulations, and protective coatings are also being developed. Sulfide ceramics show great promise because of their relatively low melting point, high-temperature viscous flow, chemical stability, high-strength bonding, and tailored coefficients of thermal expansion. Our methodology of generating laminated metal/ceramic pellets (e.g., molybdenum/sulfide ceramic/molybdenum) with which to optimize materials formulation and seal processing is described.

DoE Advanced Ceramic Microturbine  

SciTech Connect

In July 2001, Ingersoll-Rand began work on this program. Its objective was to introduce ceramic hot section components into the IR family of microturbines to permit higher operating temperatures and hence improved efficiency. The IR microturbine product line combines a novel application of industrial turbocharger equipment, our commercially successful recuperator, and proven industrial gas turbine design practices. The objective of the joint development program is to combine the high production success of the Si{sub 3}N{sub 4} turbocharger rotors, largely from Japan, with the IR turbocharger-based microturbines. The IR 'Ceramic Microturbine' (CMT) program has been configured to use the most practical ceramic rotor, considering size, geometry, proven manufacturing methods, and physical material limitations Performance predictions indicate that 36% LHV electric conversion efficiency could be attained at a Turbine Inlet Temperature (TIT) of nominally 1000 C. The initial 72kW engine is being designed to have comparable life and costs to our current product The package power rating is expandable to 100kW with this equipment by slightly increasing pressure ratio flow and TIT. This program was initially planned as five major tasks In Task 1 a comprehensive analysis of the state of the art ceramics and their applicability to microturbines was performed Milestone I was achieved with the joint DoE/IR decision to concentrate on our 70kW microturbine, with elevated turbine inlet temperature and pressure ratio,. This preserved the ability of the engine to utilize the standard IR recuperator and the majority of the microturbine subassemblies, A commercialization report, projecting the market size, was also completed as part of this task. Task 2's detailed design of the special hot-section components has been completed,. The two critical milestones, No.3 and No.4, associated with the detailed design of the monolithic silicon nitride turbine rotor and the release of the purchase order for this critical component were accomplished in Task 2. Task 3 focused on the design and release of the other non-ceramic components, including the gas generator turbine housing, the power turbine and housing, the combustor, and a new compressor section On September 4, 2002, Milestone No.4 was completed with a Detailed Design Review of the 72 kW 'Ceramic Microturbine'. The customer's concurrence at that design review triggered the release of critical components for manufacturing (Milestone 5). In Task 4, the principle components of the CMT were fabricated and delivered to our Portsmouth facility Manufacturing was mostly completed with the exception of the final machining of the GT and PT housings, the machining of the compressor diffuser, and the fabrication of the compressor cover.

Structural Ceramic Composites for Nuclear Applications  

SciTech Connect

A research program has been established to investigate fiber reinforced ceramic composites to be used as control rod components within a Very High Temperature Reactor. Two candidate systems have been identified, carbon fiber reinforced carbon (Cf/C) and silicon carbide fiber reinforced silicon carbide (SiCf/SiC) composites. Initial irradiation stability studies to determine the maximum dose for each composite type have been initiated within the High Flux Isotope Reactor at Oak Ridge National Laboratory. Test samples exposed to 10 dpa irradiation dose have been completed with future samples to dose levels of 20 and 30 dpa scheduled for completion in following years. Mechanical and environmental testing is being conducted concurrently at the Idaho National Laboratory and at Pacific Northwest National Laboratory. High temperature test equipment, testing methodologies, and test samples for high temperature (up to 1600 C) tensile strength and long duration creep studies have been established. Specific attention was paid to the architectural fiber preform design as well as the materials used in construction of the composites. Actual testing of both tubular and flat, "dog-bone" shaped tensile composite specimens will begin next year. Since there is no precedence for using ceramic composites within a nuclear reactor, ASTM standard test procedures will be established from these mechanical and environmental tests. Close collaborations between the U.S. national laboratories and international collaborators (i.e. France and Japan) are being forged to establish both national and international test standards to be used to qualify ceramic composites for nuclear reactor applications.

Space-Age Ceramics Get Their Toughest Test  

NLE Websites -- All DOE Office Websites (Extended Search)

Space-Age Ceramics Get Their Space-Age Ceramics Get Their Toughest Test Space-Age Ceramics Get Their Toughest Test Print Wednesday, 17 April 2013 07:23 Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next-generation gas-turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge-until now. Researchers have developed the first testing facility that enables microtomography of ceramic composites under controlled loads at ultrahigh temperatures and in real-time. Using this facility, they have fully resolved sequences of microcrack damage as cracks grow under load at temperatures several hundred degrees higher than previously possible. The observations are key ingredients of the high-fidelity simulations used to compute failure risks under extreme operating conditions.

Reactor vessel using metal oxide ceramic membranes  

DOE Patents (OSTI)

A reaction vessel for use in photoelectrochemical reactions includes as its reactive surface a metal oxide porous ceramic membrane of a catalytic metal such as titanium. The reaction vessel includes a light source and a counter electrode. A provision for applying an electrical bias between the membrane and the counter electrode permits the Fermi levels of potential reaction to be favored so that certain reactions may be favored in the vessel. The electrical biasing is also useful for the cleaning of the catalytic membrane.

Nanoscale Reinforced, Polymer Derived Ceramic Matrix Coatings  

Science Conference Proceedings (OSTI)

The goal of this project was to explore and develop a novel class of nanoscale reinforced ceramic coatings for high temperature (600-1000 C) corrosion protection of metallic components in a coal-fired environment. It was focused on developing coatings that are easy to process and low cost. The approach was to use high-yield preceramic polymers loaded with nano-size fillers. The complex interplay of the particles in the polymer, their role in controlling shrinkage and phase evolution during thermal treatment, resulting densification and microstructural evolution, mechanical properties and effectiveness as corrosion protection coatings were investigated. Fe-and Ni-based alloys currently used in coal-fired environments do not possess the requisite corrosion and oxidation resistance for next generation of advanced power systems. One example of this is the power plants that use ultra supercritical steam as the working fluid. The increase in thermal efficiency of the plant and decrease in pollutant emissions are only possible by changing the properties of steam from supercritical to ultra supercritical. However, the conditions, 650 C and 34.5 MPa, are too severe and result in higher rate of corrosion due to higher metal temperatures. Coating the metallic components with ceramics that are resistant to corrosion, oxidation and erosion, is an economical and immediate solution to this problem. Good high temperature corrosion protection ceramic coatings for metallic structures must have a set of properties that are difficult to achieve using established processing techniques. The required properties include ease of coating complex shapes, low processing temperatures, thermal expansion match with metallic structures and good mechanical and chemical properties. Nanoscale reinforced composite coatings in which the matrix is derived from preceramic polymers have the potential to meet these requirements. The research was focused on developing suitable material systems and processing techniques for these coatings. In addition, we investigated the effect of microstructure on the mechanical properties and oxidation protection ability of the coatings. Coatings were developed to provide oxidation protection to both ferritic and austentic alloys and Ni-based alloys. The coatings that we developed are based on low viscosity pre-ceramic polymers. Thus they can be easily applied to any shape by using a variety of techniques including dip-coating, spray-coating and painting. The polymers are loaded with a variety of nanoparticles. The nanoparticles have two primary roles: control of the final composition and phases (and hence the properties); and control of the shrinkage during thermal decomposition of the polymer. Thus the selection of the nanoparticles was the most critical aspect of this project. Based on the results of the processing studies, the performance of selected coatings in oxidizing conditions (both static and cyclic) was investigated.

Ceramic stationary gas turbine development program -- Fifth annual summary  

SciTech Connect

A program is being performed under the sponsorship of the US Department of Energy, Office of Industrial Technologies, to improve the performance of stationary gas turbines in cogeneration through the selective replacement of metallic hot section components with ceramic parts. The program focuses on design, fabrication, and testing of ceramic components, generating a materials properties data base, and applying life prediction and nondestructive evaluation (NDE). The development program is being performed by a team led by Solar Turbines Incorporated, and which includes suppliers of ceramic components, US research laboratories, and an industrial cogeneration end user. The Solar Centaur 50S engine was selected for the development program. The program goals included an increase in the turbine rotor inlet temperature (TRIT) from 1,010 C (1,850 F) to 1,121 C (2,050 F), accompanied by increases in thermal efficiency and output power. The performance improvements are attributable to the increase in TRIT and the reduction in cooling air requirements for the ceramic parts. The ceramic liners are also expected to lower the emissions of NOx and CO. Under the program uncooled ceramic blades and nozzles have been inserted for currently cooled metal components in the first stage of the gas producer turbine. The louvre-cooled metal combustor liners have been replaced with uncooled continuous-fiber reinforced ceramic composite (CFCC) liners. Modifications have been made to the engine hot section to accommodate the ceramic parts. To date, all first generation designs have been completed. Ceramic components have been fabricated, and are being tested in rigs and in the Centaur 50S engine. Field testing at an industrial co-generation site was started in May, 1997. This paper will provide an update of the development work and details of engine testing of ceramic components under the program.

Eisenbeis, Supt. of Conservation THE FIRST AMERICANS When the Norsemen and then Columbus "discovered" America they found people here -- people with bronze skins and straight black hair. Because he thought he had sailed across the world and found a sea passage to India. Columbus called these people "Indios". He was wrong but we still call them Indians. It is now generally accepted by scientists that the first humans arrived on this American continent some thirty or forty thousand years ago. It is believed that they came from Asia, across what we call Bering Strait. The distance from the islands at the westernmost tip of Alaska to the easternmost tip of Siberia is only 59 miles. In clear weather you can see from land to land. In ancient times there may have been a bridge of solid ice between the two shores, or there might have been an actual land connection between the two continents. But even if there were a 5-mile gap of water it could have been crossed in primitive canoes by hungry people hunting for game. Hunger has been the mainspring of civilization.

Chemically bonded phospho-silicate ceramics  

DOE Green Energy (OSTI)

A chemically bonded phospho-silicate ceramic formed by chemically reacting a monovalent alkali metal phosphate (or ammonium hydrogen phosphate) and a sparsely soluble oxide, with a sparsely soluble silicate in an aqueous solution. The monovalent alkali metal phosphate (or ammonium hydrogen phosphate) and sparsely soluble oxide are both in powder form and combined in a stochiometric molar ratio range of (0.5-1.5):1 to form a binder powder. Similarly, the sparsely soluble silicate is also in powder form and mixed with the binder powder to form a mixture. Water is added to the mixture to form a slurry. The water comprises 50% by weight of the powder mixture in said slurry. The slurry is allowed to harden. The resulting chemically bonded phospho-silicate ceramic exhibits high flexural strength, high compression strength, low porosity and permeability to water, has a definable and bio-compatible chemical composition, and is readily and easily colored to almost any desired shade or hue.

Method for producing ceramic particles and agglomerates  

DOE Patents (OSTI)

A method for generating spherical and irregularly shaped dense particles of ceramic oxides having a controlled particle size and particle size distribution. An aerosol containing precursor particles of oxide ceramics is directed into a plasma. As the particles flow through the hot zone of the plasma, they melt, collide, and join to form larger particles. If these larger particles remain in the hot zone, they continue melting and acquire a spherical shape that is retained after they exit the hot zone, cool down, and solidify. If they exit the hot zone before melting completely, their irregular shape persists and agglomerates are produced. The size and size distribution of the dense product particles can be controlled by adjusting several parameters, the most important in the case of powder precursors appears to be the density of powder in the aerosol stream that enters the plasma hot zone. This suggests that particle collision rate is responsible for determining ultimate size of the resulting sphere or agglomerate. Other parameters, particularly the gas flow rates and the microwave power, are also adjusted to control the particle size distribution.

Low heat rejection diesel ceramic coupon tests  

DOE Green Energy (OSTI)

Results are reported from studies in which several monolithic ceramic materials in the form of modulus-of-rupture bars were exposed for 100 h to the combustion conditions found in either a small single- or two-cylinder diesel engine. Fuels included a standard Phillips D-2 diesel or synthetic mixture of the Phillips D-2 and an aromatic blend. The ceramics included two commercial grades of partially stabilized zirconia: (1) PSZ-TS and (2) PSZ-MS and silicon nitride (GTE WESGO SNW-1000 and Norton NT-154). Significant reductions in postexposure four-point bend fracture strength occurred in the PSZ-TS material irrespective of whether it was exposed in the single- or two-cylinder engine. Only a small decrease in fracture strength occurred in the PSZ-MS material, and essentially no decrease in fracture strength occurred in the silicon nitride (GTE WESGO SNW-1000) when tested at room temperature. The Norton NT-154 silicon nitride was tested at both room temperature and at 700{degree}C over several strain rates ranging from 1 {times} 10{sup {minus}4} to 1 {times} 10{sup {minus}7}S{sup {minus}1}. Room temperature tests showed that the engine exposed bars actually showed a slight increase in average strength, 830 MPa, versus 771 MPa for the unexposed material. 6 figs., 1 tab.

Nondestructive characterization of structural ceramic components  

DOE Green Energy (OSTI)

Advanced structural ceramic components under development for heat-engine applications include both monolithic and continuous fiber composites (CFC). Nondestructive characterization (NDC) methods being developed differ for each material system. For monolithic materials, characterization during processing steps is important. For many CFC, only post process characterization is possible. Many different NDC systems have been designed and built A 3D x-ray micro computed tomographic (3DXCT) imaging system has been shown to be able to map density variations to better than 3% in pressure slip cast Si{sub 3}N{sub 4} monolithic materials. In addition, 3DXCT coupled to image processing has been shown to be able to map through-thickness fiber orientations in 2D lay-ups of 0{degrees}/45{degrees}, 0{degrees}/75{degrees}, 0{degrees}/90{degrees}, in SiC/SiC CVI CFC. Fourier optics based laser scatter systems have been shown to be able to detect surface and subsurface defects (as well as microstructural variations) in monolithic Si{sub 3}N{sub 4} bearing balls. Infrared methods using photothermal excitation have been shown to be able to detect and measure thermal diffusivity differences on SiC/SiC 2D laminated CFC which have been subjected to different thermal treatments including thermal shock and oxidizing environments. These NDC methods and their applications help provide information to allow reliable usage of ceramics in advanced heat engine applications.

Exposure of Ceramics and Ceramic Matrix Composites in Simulated and Actual Combustor Environments  

DOE Green Energy (OSTI)

A high-temperature, high-pressure, tube furnace has been used to evaluate the long term stability of different monolithic ceramic and ceramic matrix composite materials in a simulated combustor environment. All of the tests have been run at 150 psia, 1204 degrees C, and 15% steam in incremental 500 h runs. The major advantage of this system is the high sample throughput; >20 samples can be exposed in each tube at the same time under similar exposure conditions. Microstructural evaluations of the samples were conducted after each 500 h exposure to characterize the extent of surface damage, to calculate surface recession rates, and to determine degradation mechanisms for the different materials. The validity of this exposure rig for simulating real combustor environments was established by comparing materials exposed in the test rig and combustor liner materials exposed for similar times in an actual gas turbine combustor under commercial operating conditions.

Compatibility of selected ceramics with steam-methane reformer environments  

DOE Green Energy (OSTI)

Conventional steam reforming of methane to synthesis gas (CO and H{sub 2}) hasa conversion efficiency of about 85%. Replacement of metal tubes in the reformer with ceramic tubes offers the potential for operation at temperatures high enough to increase the efficiency to 98-99%. However, the two candidate ceramic materials being given strongest consideration, sintered alpha Si carbide and Si carbide particulate-strengthened alumina, have been shown to react with components of the reformer environment. Extent of degradation as a function of steam partial pressure and exposure time has been studied, and results suggest limits under which these structural ceramics can be used in advanced steam-methane reformers.

The early colonists found huge patriarchs, which reminded them of the magnificent English Elms, and they planted seedlings to shade their homes and village commons. Today, innumerable New England roadways are lined with giant elms, their great arching limbs forming canopies like a cathedral roof. When the pioneers moved westward, they found this tree everywhere in the bottomlands and on low fertile hills. NOW, throughout the Middle West -- even in prosaic prairie towns -- streets and public buildings are shaded and given character by beautiful elms.

The purpose of this workshop was to present a preliminary project plan for industry critique and to identify specific components and cost-reduction targets for a new project on Cost Effective Ceramic Machining. The CECM project is an extension of the work on the Ceramic Technology for Advanced Heat Engines (CTAHE) Program sponsored by the Department of Energy, Office of Transportation Materials. The workshop consisted of fifteen invited papers, discussions, a survey of the attendee`s opinions, and a tour of the High Temperature Materials Laboratory at ORNL. The total number of registrants was sixty-seven, including thirty-three from industry or private sector organizations, seven from universities, three from industry groups, fourteen from DOE laboratories (including ORNL, Y-12, and Lawrence Livermore Laboratory), three from trade associations, and three from other government organizations. Forty- one survey forms, which critiqued the proposed project plan, were completed by attendees, and the results are presented in this report. Valves, cam roller followers, water pump seals, and diesel engine head plates were rated highest fro application of ceramic machining concepts to reduce cost. Coarse grinding, abrasives and wheel technology, and fine grinding were most highly rated as regards their impact on cost reduction. Specific cost-reduction targets for given parts varied greatly in the survey results and were not felt to be useful for the purposes for the CECM plan development. A range of individual comments were obtained and are listed in an appendix. As a result of the workshop and subsequent discussions, a modified project plan, different in certain aspects from the original CECM plan, has been developed.

Advanced Radiation-Resistant Ceramic Composites  

SciTech Connect

Ceramic matrix composites (CMC), particularly silicon carbide (SiC) fiber-reinforced SiC-matrix (SiC/SiC) composites, have been studied for advanced nuclear energy applications for more than a decade. The perceived potentials for advanced SiC/SiC composites include the ability to operate at temperature regimes much higher than heat-resistant alloys, the inherent low induced-activation nuclear properties, and the tolerance against neutron irradiation at high temperatures. This paper reviews the recent research and development of the advanced radiation-resistant SiC/SiC composites for nuclear applications. Additionally, remaining general and specific technical issues for SiC/SiC composites for nuclear applications are discussed.

RUGGED CERAMIC WINDOW FOR RF APPLICATIONS  

Science Conference Proceedings (OSTI)

High-current RF cavities that are needed for many accelerator applications are often limited by the power transmission capability of the pressure barriers (windows) that separate the cavity from the power source. Most efforts to improve RF window design have focused on alumina ceramic, the most popular historical choice, and have not taken advantage of new materials. Alternative window materials have been investigated using a novel Merit Factor comparison and likely candidates have been tested for the material properties which will enable construction in the self-matched window configuration. Window assemblies have also been modeled and fabricated using compressed window techniques which have proven to increase the power handling capability of waveguide windows. Candidate materials have been chosen to be used in fabricating a window for high power testing at Thomas Jefferson National Accelerator Facility.
