综述了钙钛矿结构的Na0.5Bi0.5TiO3(简称BNT)基无铅压电陶瓷的研究现状,并与其它无铅基压电陶瓷进行了对比。列举了近年来BNT基压电陶瓷的新发展和热门体系,结合笔者承担的相关研究工作内容,总结和指出了BNT基无铅压电陶瓷新的研究思路和相关方向。
The recent progresses of perovskite BNT-based lead-free piezoelectric ceramics were reviewed in this paper, and compared with other lead-free piezoelectric ceramics, enumerated the development of BNT-based lead-free piezoelectric ceramics recently and hot systems. The new design principle for BNT- based lead free piezoelectric ceramics was also summarized.
