Zn-Zr共掺对0.95MgTiO3-0.05CaTiO3陶瓷介电性能的影响
Influence of Zn-Zr codoping on dielectric properties of 0.95MgTiO3-0.05CaTiO3 ceramics
摘要
Abstract
(Mg0.95Ca0.05Zn0.02)(Ti1-xZrx)O3 ceramics were prepared using the conventional solid-state method. The effects of Zn-Zr addition on the dielectric properties of the 0.95MgTiO3-0.05CaTiO3(95MCT) ceramics were investigated. The results show that Zn-Zr additive can lower the sintering temperature Of 95MCT ceramics to 1 300 ℃, and improve the dielectric properties. Moreover, it also effectively adjusts the temperature coefficient of permittivity(αc). The 95MCT ceramics with mole fraction of 0.02 (Zn2+ and Zr4+) possess excellent dielectric properties: εr of 22.02 (1 MHz), tanδ of 2.78 × 10-4 and αc value of 2.98 × 10-6/℃关键词
