采用常规的陶瓷工艺制备了BaWO4/(Ba,Sr)TiO3复合陶瓷,并通过X射线衍射、扫描电镜及介电性能测试对陶瓷的烧结特性、微结构和介电性能进行了研究.结果表明,BaWO4/(Ba,Sr)TiO3复合陶瓷在1250～1300℃可以实现致密化烧结,且陶瓷由(Ba,Sr)TiO3和BaWO4两相复合而成,未检测到其它物相.随着BaWO4含量的增加,材料的表观密度逐渐增大,介电常数和可调度逐渐降低,介电损耗变化不大,均在10-3量级.典型样品(60%BaWO4/40 0ABa0.5Sr0.5TiO3,质量分数)介电常数182.7,介电损耗0.0024,在2 V·μm-1偏置电场下的可调度为14.7%,具有较好的介电性能.
