NBT基无铅压电陶瓷的研究进展

RESEARCH PROGRESS IN NBT BASED LEAD-FREE PIEZOELECTRIC CERAMICS

由于环境保护的要求 ,无铅压电材料越来越受到关注 ,NBT基压电陶瓷是目前研究较多的一种无铅压电材料 ,采取各种掺杂措施可以提高其压电性能 ,获得具有实用价值的无铅压电陶瓷材料。

The lead-free piezoelectric material becomes more and more important for the request of environmental protection.Much research has been done on NBT based piezoelectric ceramics so far.A lead-free piezoelectric ceramics with application value can be acquired by the doping of the NBT based ceramics.
