Abstract:

采用传统电子陶瓷工艺制备出BaSrZnSi2O7-Ba0.5Sr0.5TiO3复合陶瓷,系统研究了其相结构、微观结构和介电性能。研究表明:随着BaSrZnSi2O7的加入,样品的居里峰向低温方向移动;但BaSrZnSi2O7加入量达到一定程度后,居里峰在一定的温度下保持稳定。调制特性变化规律类似于居里峰的移动。品质因数(Q值)的变化主要取决于微波材料加入后的"掺杂"和"复合"效果。当BaSrZnSi2O7质量分数为60wt%时,复合材料表现出良好的综合特性:介电可调率为16%(10kHz),介电常数为152,Q值达到417(2.720GHz),表明BaSrZnSi2O7-Ba0.5Sr0.5TiO3复合陶瓷是电可调微波器件很好的潜在应用材料。
