溶胶-凝胶法与固相法制备BCZT陶瓷的结构与电学性能探究
Study on the structure and electrical properties of BCZT ceramics prepared by sol-gel method and solid phase method
摘要
Abstract
Ba0.85Ca0.15Zr0.1Ti0.9O3(BCZT)powder was prepared by a modified sol-gel method and traditional solid phase method,respectively.BCZT ceramics were prepared by a solid state reaction process at different sintering temperatures.The reaction process and structure of sol-gel powder were tested by X-ray diffraction,FT-IR spectrometer and thermal analyzer.The sintering process of ceramic was investigated by a high temperature image sintering instrument.The results showed that the best calcination temperature of BCZT powder prepared by sol-gel method was 900 ℃,the best sintering temperature of ceramic was 1400 ℃;While the best sintering temperature of ceramic prepared by solid phase method was 1500 ℃.The electrical property analysis showed that the relative permittivity and the remnant polarization of ceramics prepared by sol-gel method were 11 082.5 and 9.80 μC/cm2,respectively.The electrical properties of BCZT ceramics prepared by sol-gel process were greatly improved compared with those prepared by solid phase method.关键词
