烧结温度对Zn-Nb共掺Ba(Zr0.1Ti0.9)O3陶瓷微结构与介电性能的影响
Influence of sintering temperature on microstructure and dielectric property of Zn-Nb co-doped Ba(Zr0.1Ti0.9)O3ceramics
摘要
Abstract
The Zn and Nb co-doped Ba(Zr0.1Ti0.9)O3 ceramics were prepared by sol-gel method and the effect of sintering temperature on their phase structure,microstructure,electrical properties and dielectric relaxation was investigated. All sintered samples present a tetragonal perovskite structure and met the Electronic Industries Alliance Y5V specifications. As the sintering temperature increases, the maximum dielectric constant and grain sizes increase; while the dispersion coefficient of phase transformation(γ) first increases and then decreases. The ceramics sintered at 1280℃ exhibite permittivity of 14849 and tangent loss of 0.37%,with the average particle size of 3μm,a maximumγ of 1.9092, and a maximum density of 6.0346 g/cm3.关键词
