锆钛酸锶钙陶瓷材料主晶相组份与介电性能

Ca_xSr_(1-x)(Ti_(1-y)Zr_y)_zO_3 NPO Ceramics Material Main Crystal Component And Electricity Properties

采用固相法制备了CaxSr(1-x)〔Ti(1-y)Zry〕zO3(CSTZ锆钛酸锶钙)陶瓷,研究CSTZ系统陶瓷材料的组成与介电性能的关系。结果表明:当x为0.45,y为0.88,z为1.05时,主晶相CaxSr(1-x)〔Ti(1-y)Zry〕zO3形成完全互溶钙钛矿型固溶体。可获得具有理想介电性能、不含Pb和Cd等有害杂质的抗还原高频MLCC瓷料。

CaxSr（1-x）[Ti（1-y）Zry]zO3（CSTZ）ceramics were prepared by the solid state method.The relationship between dielectric properties and composition of CSTZ ceramic powder were investigated.The results show that under the conditions x is 0.45,y is 0.88,z is 1.05,CaxSr（1-x）[Ti（1-y）Zry]zO3 system forms the completely and mutually soluble perovskite-type materials as main crystal phase.Good quality anti-reducing NPO-MLCC ceramic powder no using Pb and Ge additives can be gotten.
