Abstract

采用固相反应法制备Bi 1.5- x Ca x ZnNb 1.5 O 7 (0≤ x ≤0.50, BCZN)陶瓷, 研究Ca 2+ 替代Bi 3+ 对Bi 1.5 ZnNb 1.5 O 7 陶瓷烧结特性、显微结构、介电性能和结晶化学特性的影响. 结果表明: 替代量x≤0.25 mol时, 样品为单一的α-BZN相. 随着Ca 2+ 替代量增加, 样品最佳烧结温度从1000℃升高到1020℃; 致密度从7.011 g/cm 3 减小到6.353 g/cm 3 ; 样品晶粒尺寸、晶格常数、电阻率均减小; 结晶化学参数键价和, AV (O')[Bi 4 ]、 AV (O')[Bi 3 Zn]、 AV (O')[Bi 2 Zn 2 ]和 AV (O')[Ca 3 Zn]均增大, 且该行为与其晶格常数、介电性能变化相吻合.
