摘　　要：随着高新技术的迅速发展,对压电器件工作温度的要求越来越高,因此高温压电陶瓷材料成为近几年研究的热点之一。介绍了国内外学者对钙钛矿结构、钨青铜结构和铋层状结构压电陶瓷进行改性,获得一系列高温压电陶瓷材料的研究现状。展望了高温压电陶瓷材料的发展前景,并对其今后的研究方向提出了建议。Along with the rapid development of high-technology, the operation temperature of piezoelectric devices are getting higher and higher, consequently, the high temperature piezoceramics has become one of the research focuses of piezoceramics. In this paper, the research status of modified perovskite, tungsten bronze and bismuth layer structure of high temperature piezoceramics is introduced. The prospect of the high temperature piezoceramics is presented, and suggestions for its future research are made
