摘　　要：就Sm部分取代BiNbO4陶瓷中的Bi对其烧结性能及微波介电性能的影响进行了研究。实验结果发现,随Sm取代量的增加,BiNbO4陶瓷的烧结温度升高,其晶相组成及微波介电性能也随之改变。通过适量的取代,可以获得各项性能均较优异的微波介质陶瓷材料组成。Sm was substituted for Bi in BiNbO4 ceramics and the effects on the sintering behavior and microwave dielectric properties have been investigated. The result show that with increase of Sm content, the sintering temperature increases and the crystalline phase and microwave dielectric properties change. The compositions exhibiting excellent microwave properties can be obtained by controlling the Sm constant in BiNbO4 ceramics.
