本文采用流延成型法制备2-2型Ba2Ti9O20-BaFe12O19复合陶瓷.通过扫描电镜、能量散射光谱仪、X射线衍射、振动样品磁强计对复合陶瓷界面微观结构及磁、电性能进行了分析.结果表明:复合陶瓷的介电常数和介电损耗均大于单相Ba2Ti4O20,饱和磁化强度、剩余磁化强度均小于单相BaFe12 O19,矫顽力大于单相BaFe12O19.随着烧结温度的升高,复合陶瓷的介电常数先增加后减小,介电损耗的变化则相反；饱和磁化强度、剩余磁化强度和矫顽力减小.在1180℃烧结4h的复合陶瓷具有适合的磁、电性能:εx=115,tanδ=0.0054,Ms=21.9 A·m2/kg,Mr=12.5A·m2/kg和Hc=63.0kA/m.
