Abstract

SEM micrographs for the pure CaO–MgO–Al{sub 2}O{sub 3}–SiO{sub 2} glass sintered at 850–1000 °C (a) 850 °C, (b) 900 °C, (c) 950 °C, (d) 1000 °C. - Highlights: • ZrO{sub 2} effects on the crystallization of LTCC glass system were investigated. • ZrO{sub 2} effects on the dielectric properties of LTCC glass system were investigated. • LTCC with a dielectric constant of 6.65 and a low dielectric loss can be obtained. - Abstract: The zirconium oxide effects on the crystallization and dielectric properties of CaO–MgO–Al{sub 2}O{sub 3}–SiO{sub 2} (CMAS) glass were investigated. The results showed that phyllosiloxide and anorthite crystallites were observed in sequence during sintering. For glass added with 8 wt% ZrO{sub 2}, homogeneously dispersed tetragonal ZrO{sub 2} crystallites were observed at 850 °C. The as-prepared CMAS glass–ceramics exhibited a dielectric constant of about 6–7 and a dielectric loss below 0.005 at 100 MHz. The dielectric properties of CMAS glass with 8 wt% ZrO{sub 2} sintered at 850 °C show a low dielectric constant of 6.65 and a dielectric loss tangent of about 2.5 × 10{sup −3}, which provides a promising candidate for LTCC applications.

Zirconia nucleating agent on microstructural and electrical properties of a CaMgSi{sub 2}O{sub 6} diopside glass–ceramic for microwave dielectrics

Journal Article Feng, Kuei-Chih; Chou, Chen-Chia; Chu, Li-Wen; ... - Materials Research Bulletin

Addition of different amount of zirconia (ZrO{sub 2}) nucleating agent into MgO–CaO–SiO{sub 2} system to enhance the quality factor (Q × f) of CaMgSi{sub 2}O{sub 6} diopside glass–ceramic for low sintering temperature process (from 850 to 950 °C) was carried out in this work. The microstructures, microwave dielectric properties and nucleating/growth mechanism of m-ZrO{sub 2} added CaMgSi{sub 2}O{sub 6} system were analyzed using transmission electron microscopy (TEM) and electrical property measurements. Experimental results demonstrate that a solid solution of an amorphous phase MgO–CaO–SiO{sub 2} and ZrO{sub 2} forms after melted at 1500 °C. The t-ZrO{sub 2} appears in the amorphousmore »« less

Preparation of LTCC materials with adjustable permittivity based on BaO–B{sub 2}O{sub 3}–SiO{sub 2}/BaTiO{sub 3} system

Journal Article Wang, Kai-tuo; He, Yan; Liang, Zhong-yuan; ... - Materials Research Bulletin

Graphical abstract: The dielectric constant (ϵ) of the sintered BaO–B{sub 2}O{sub 3}–SiO{sub 2}/BaTiO{sub 3} glass/ceramics (the sintered samples with line shrinkage of 10%) changed from 5 to 30 and the dielectric losses (tanδ) was lower than 0.05 at 100 MHz with the amount of BaTiO{sub 3} additive increment from 60 wt% to 90 wt% fraction. - Highlights: • The ϵ of BaO–B{sub 2}O{sub 3}–SiO{sub 2} glass can be adjusted from 5 to 30 by adding BaTiO{sub 3}. • The influence factors on dielectric are the secondary phase and microstructure. • BaO–B{sub 2}O{sub 3}–SiO{sub 2}/BaTiO{sub 3} system can fabricate LTCC whenmore »« less

Study on properties of CaO-SiO{sub 2}-B{sub 2}O{sub 3} system glass-ceramic

Journal Article Haikui, Zhu; Min, Liu; Hongqing, Zhou; ... - Materials Research Bulletin

Low temperature co-fired ceramic (LTCC) is prepared by sintering a glass selected from CaO-SiO{sub 2}-B{sub 2}O{sub 3} system, and its sintered bodies are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). It is found that the optimal sintering temperature for this glass-ceramic is 820 deg. C for 15 min, and the major phases of this material are CaSiO{sub 3}, CaB{sub 2}O{sub 4} and SiO{sub 2}. The glass-ceramic possesses excellent dielectric properties: {epsilon} {sub r} = 6.5, tan {delta} < 2 x 10{sup -3} at 10 MHz, temperature coefficient of dielectric constant about -51 xmore »« less
Composition and Structure of Block-Type Ferrospheres Isolated from Calcium-Rich Power Plant Ash

Journal Article Anshits, N.; Fedorchak, M.; Zhizhaev, A.; ... - Inorganic Materials

Polished sections of individual ferrospheres 30 to 40 μm in size, with single-block and blocky structures and a variable glass phase content, have been studied using a scanning electron microscope equipped with an energy dispersive X-ray spectrometer system. The results demonstrate that the single-block globules consist of sintered magnetite crystallites containing Al{sub 2}O{sub 3}, MgO, and CaO as impurities and are formed from the pyrite of the initial coal. Characteristically, the ferrospheres with a variable glass phase content differ in the composition of local areas on polished sections of the globules, which attests to inhomogeneity of the melt droplets theymore »« less

Effect of B{sub 2}O{sub 3}-Bi{sub 2}O{sub 3}-SiO{sub 2}-ZnO glass on the sintering and microwave dielectric properties of 0.83ZnAl{sub 2}O{sub 4}-0.17TiO{sub 2}

Journal Article Thomas, Sherin - Materials Research Bulletin

The 0.83ZnAl{sub 2}O{sub 4}-0.17TiO{sub 2} (ZAT) ceramics were synthesized by solid state ceramic route. The effect of 27B{sub 2}O{sub 3}-35Bi{sub 2}O{sub 3}-6SiO{sub 2}-32ZnO (BBSZ) glass on the microwave dielectric properties of ZAT was investigated. The crystal structure and the microstructure of the ceramic-glass composites were studied by X-ray diffraction and scanning electron microscopic techniques. The low frequency dielectric loss was measured at 1 MHz. The dielectric properties of the sintered samples were measured in the microwave frequency range by the resonance method. Addition of 0.2 wt% of BBSZ improved the dielectric properties with quality factor (Q{sub u} x f) >more »« less
