采用标准电子陶瓷工艺制备了(Mg0.95Zn0.05)2(Ti0.8Sn0.2)O4陶瓷.研究了(Mg0.95Zn0.05)2(Ti0.8Sn0.2)O4陶瓷的烧结特性、相结构和微波介电性能.采用X射线衍射分析其物相组成,利用SEM观察其显微结构.XRD图谱表明烧结样品为立方尖晶石( Mg0.95Zn0.05)2(Ti0.8Sn0.2 )O4结构,晶胞参数为a=b=c=0.848794nm.实验结果表明,随烧结温度升高,样品相对介电常数(εr)和品质因数(Q·f)先增加后减小,谐振频率温度系数(τf)变化不大.1325℃/5h烧结样品具有优良微波介电性能:εr=13.1,Q·f=131170GHz(10GHz)、τf=-55.6×10-6/℃.
