摘　　要：用两相混合烧结法制备了 PZN基和 BT基复合的复相陶瓷。研究了起始两相的比例以及粉末的粒度和烧成条件对复相陶瓷介电性能的影响。通过优化工艺条件 ,获得了满足 X7R(ΔC/ C<± 15 % ,- 5 5～ 12 5°C)The biphasic ceramics composed of PZN based and BT based constitutes were prepared by two phases mixed sintering method.The effects of the ratios of two starting constitutes,the particles of powders and sintering conditions on dielectric properties of biphasic ceramics were studied.The X7R(Δ C/C <±15%,-55～125 °C)temperature stable biphasic dielectric ceramics were developed by improving processing conditions.
