摘　　要：为适应人们对环保压电陶瓷的迫切需求,分析综合各类压电材料的结构和性能为研究和应用提供理论依据。重点介绍了已引起人们关注的钛酸钡基、铋层状结构、钛酸铋钠基、铌酸盐基无铅压电陶瓷体系的研究现状和应用。在性能方面,这些材料和传统的PZT基压电陶瓷都有各自的特点。目前的无铅压电陶瓷虽然不能完全取代PZT基压电陶瓷,但对其的研究已取得很大进展。To meet people's urgent needs of environmental protection piezoelectric ceramics,a comprehensive analysis of various types of lead-free piezoelectric ceramic materials for the study of the structure and properties and applications provide a theoretical basis.Focuses on the cause for concern has been based barium titanate,bismuth layered structure,bismuth sodium titanate,niobate-based lead-free piezoelectric ceramics of Research and applications.In terms of performance,these materials and traditional PZT-based piezoelectric ceramics have their own characteristics.Although the current lead-free piezoelectric ceramics can not completely replace PZT-based piezoelectric ceramics,but their research has made great progress.
