摘要
介绍了铋层状无铅压电陶瓷的结构及其性能改进方法,着重综述了(Bi_2O_2)^(2+)(AB_2O_7)^(2-)基,(Bi_2O_2)^(2+)(A_2B_3O_(10))^(2-)基及(Bi_2O_2)^(2+)(A_3B_4O_(13))^(2-)基压电材料的改性研究进展。对于开发新的具有高压电活性及高居里温度的无铅铋层状压电陶瓷具有借鉴意义,对制备高温压电传感器的选材具有一定的参考价值。
In this paper,the structure and performance modification methods of bismuth structure lead-free piezoelectric ceramics were introduced,and the research progresses of modification of (Bi2O2)^2+(AB2O7)^2--based,(Bi2O2)^2+(A2B3O10)^2--based and (Bi2O2)^2+(A3B4O13)^2--based piezoelectric materials were analyzed. This paper is of great significance not only for finding a new bismuth structure lead-free piezoelectric ceramics with high Curie temperature and high piezoelectric activity,but also for selecting piezoelectric materials to prepare high temperature piezoelectric sensors.
