摘要
兼具优异压电性能和高居里温度(tC)的压电陶瓷在高温极端环境条件下具有非常重要的用途,是当今压电铁电材料研究热点之一。简要总结了压电陶瓷的居里温度、压电介电性能等的影响因素,重点介绍钙钛矿结构BiScO_3-PbTiO_3(BSPT)二元体系,从离子取代、化合物复合、氧化物掺杂等方面归纳总结该体系的改性研究进展。
The piezoelectric ceramics with outstanding piezoelectric properties and high Curie temperature are significantly applied to the severe condition of high temperature, and it is one of the mostly researched piezoelectric and ferroelectric ceramics nowadays. It is briefly summarized that the factors influence the curie temperature and piezoelectric,dielectric properties of piezoelectric ceramics, focused on binary system of BiScO3-PbTiO3 (BSPT) with perovskite structure, where the researching progress of the modification is summarized from the aspects of ionic substitution,compound composite, oxide doping.
