摘要
本文介绍了铋层状结构无铅压电材料的研究现状及存在的问题。铋层状结构无铅压电材料居里温度较高,可以用于高温压电方面的应用,但其压电性能较差。本文重点介绍了提高铋层状结构无铅压电材料压电性能的措施——晶粒定向生长和掺杂。
This paper introduces the present situation and existing problems of bismuth layer structure lead-free piezoelectric material,the curie temperatures of which are very high,so they can be used in high temperature piezoelectric application.But their piezoelectric property is poor.Several processings,grain orientation growth (TGG) and doping,which can improve performance of the bismuth layer structure lead-free piezoelectric material,are introduced.
