Abstract
采用固相法制备了（1-x）CaTi03-xLi1／2Sm1／2TiO3系列微波介质陶瓷材料，研究了该体系的相组成、烧结性能和微波介电性能之间的关系．结果表明：在x=0．1—0．9tool范围内，（1-x）CaTi03-x（Li1／2Sm1／2）TiO3体系均形成了单一的斜方钙钛矿结构；x=0．1—0．5和x=0．6—0．9组分的最佳烧结温度分别为1250和1300℃；介电常数er、无载品质因数与谐振频率乘积Qf值、谐振频率温度系数Tf均随着x的增大而减小．当x=0．7时，1300℃下保温5h烧结得到的材料的微波介电性能为：er=116．5，Qf=3254GHz，Tf=42．43×10^-6／℃．
