Abstract

In this study, to evaluate the feasibility of molybdenum as light water reactor nuclear fuel cladding, the oxidation behavior was tested in water vapor at elevated temperatures. We present experimental results on the oxidation and volatilization of molybdenum using various characterization techniques including grazing incidence X-ray diffraction and transmission electron microscopy. After oxidation testing in water vapor at 600 °C, experiment results show the formation of both MoO₃ and MoO₂. Lastly, with the increasing temperature, MoO₂ is the final oxidation product between 800 and 1200°C, and MoO₃ is volatile at these temperatures.

Oxidation, volatilization, and redistribution of molybdenum from TZM alloy in air

Technical Report Smolik, G R ; Petti, D A ; McCarthy, K A ; ...

The excellent high temperature strength and thermal conductivity of molybdenum-base alloys provide attractive features for components in advanced magnetic and inertial fusion devices. Refractory metal alloys react readily with oxygen and other gases. Oxidized molybdenum in turn is susceptible to losses from volatile molybdenum trioxide species, MoO{sub 3}(m), in air and the hydroxide, MoO{sub 2}(OH){sub 2}, formed from water vapor. Transport of radioactivity by the volatilization, migration, and re-deposition of these volatile species during a potential accident involving a loss of vacuum or inert environment represents a safety issue. In this report the authors present experimental results on the oxidation,more »« less

Preparation of amorphous electrochromic tungsten oxide and molybdenum oxide by plasma enhanced chemical vapor deposition

Journal Article Tracy, C E ; Benson, D K - J. Vac. Sci. Technol., A; (United States)

Preliminary experiments have been performed to probe the feasibility of using plasma enhanced chemical vapor deposition (PE--CVD) to prepare electrochromic thin films of tungsten oxide and molybdenum oxide by plasma reaction of WF/sub 6/, W(CO)/sub 6/, and Mo(CO)/sub 6/ with oxygen. Thin films produced in a 300 W, electrodeless, radio-frequency (rf), capacitive discharge were found to be electrochromic when tested with either liquid or solid electrolytes. Optical spectroscopy was performed on two electrochromic coatings after Li/sup +/ ion insertion from a propylene carbonate liquid electrolyte. Broad absorption peaks at --900 nm for WO/sub 3/ and 600 nm for MoO/sub 3/more »« less

Oxidation and volatilization of TZM alloy in air

Conference Smolik, G R ; Petti, D A ; Schuetz, S T

The excellent high temperature strength and thermal conductivity of molybdenum-base alloys provide attractive features for components in advanced magnetic and inertial fusion devices. Refractory metal base alloys react readily with oxygen and other gases, and molybdenum alloys are susceptible to losses from highly volatile molybdenum trioxide (MoO{sub 3}) species. Transport of radioactivity by the volatilization, migration, and re-deposition of MoO{sub 3} during a potential accident involving a loss of vacuum or inert environment represents a safety issue. The authors have experimentally measured the oxidation, volatilization and re-deposition of molybdenum from TZM in flowing air between 400 and 800 C. Calculationsmore »« less

Relationship between electrical properties and crystallization of indium oxide thin films using ex-situ grazing-incidence wide-angle x-ray scattering

Journal Article González, G. B. ; Okasinski, J. S. ; Buchholz, D. B. ; ... - Journal of Applied Physics

Grazing-incidence, wide-angle x-ray scattering measurements were conducted on indium oxide thin films grown on silica substrates via pulsed laser deposition. Growth temperatures (T_G) in this study ranged from -50 °C to 600 °C, in order to investigate the thermal effects on the film structure and its spatial homogeneity, as well as their relationship to electrical properties. Films grown below room temperature were amorphous, while films prepared at T_G = 25 °C and above crystallized in the cubic bixbyite structure, and their crystalline fraction increased with deposition temperature. The electrical conductivity (σ) and electrical mobility (μ) were strongly enhanced at lowmore »« less

A study of the reactivity of reduced molybdenum ethoxides: Synthesis and characterization of MoO(OH) and some novel molybdenum ethoxide cluster molecules

Thesis/Dissertation Hollingshead, J S

A low temperature route was used in an attempt to produce reduced molybdenum oxides. When molybdenum (III) ethoxide was hydrolyzed with the stoichiometric amount of water in hydrocarbon solvent, a quantitative yield of product was recovered. Elemental and molybdenum oxidation state analyses on this material indicated an empirical formula of Mo{sub 2}(OH){sub 5}(OEt). When this material was heated in the presence of hydrogen at 250{degrees}C, a black solid was produced. Analyses indicated the material is MoO(OH). All attempts to thermally decompose MoO(OH) to the oxide, Mo{sub 2}O{sub 3}, were unsuccessful. A mixture of Mo{sub 2}O{sub 3} and MoO{sub 2} wasmore »« less
