摘要
用两相混合烧结法分别制备了Ｐｂ（Ｚｎ１／３Ｎｂ２／３）Ｏ３系和Ｐｂ（Ｎｉ１／３Ｎｂ２／３）Ｏ３系复合陶瓷。介电性能测试结果表明，Ｐｂ（Ｚｎ１／３Ｎｂ２／３）Ｏ３系陶瓷材料中保持了两相共存的复相结构，而Ｐｂ（Ｎｉ１／３Ｎｂ２／３）Ｏ３系陶瓷材料中却难以获得两相共存的复相结构。
Pb(Zn1/3Nb2/3)O3-based and Pb(Ni1/3Nb2/3)O3-based composite ceramics were prepared by mixed sintering method.The dielectric measurements showed that Pb(Zn1/3Nb2/3)O3-based ceramic has diphasic structure and Pb(Ni1/3Nb2/3)O3-based ceramic has not.The reasons were explained according to crystal chemistry and diffusion kinetics.
