采用固相反应法合成了(1-x)CaTiO3/xNi0.5Zn0.5Fe2O4(0≤x≤1.0)复合材料,并研究了复合材料的物相、微观结构、介电性能和磁性能.结果表明:样品中仅含有钙钛矿型CaTiO3和尖晶石型Ni0.5Zn0.5Fe2O4.1260℃保温3h,样品相对密度达到98.91％,颗粒尺寸约为2μm.样品介电常数随Ni0.5Zn0.5Fe2O4含量(x)增加而增大.当x=0.7、测试频率为103Hz时,样品介电常数(εr)和介电损耗(tanδ)分别为2629.18和1.74.(1-x)CaTiO3/xNi0.5Zn0.5Fe2O4复合材料显示磁性.其中x=0.7时,样品饱和磁化强度(Ms)达到49.07A·m2/kg;这归因于Ni0.Zn0.5Fe2O4具有优异的磁性能.
