摘　　要：介绍了铋层状结构无铅压电陶瓷、钨青铜结构无铅压电陶瓷、钙钛矿结构无铅压电陶瓷(包括钛酸铋钠Bi_(0.5)Na_(0.5)TiO_3(BNT)基、碱金属铌酸盐K_(0.5)NaO_5NbO_3(KNN)基、钛酸钡BaTiO_3(BT)基压电陶瓷)等不同陶瓷体系的制备方法、压电性能、应用领域及最新进展。最后就无铅压电陶瓷今后的研究提出了几点建议。The development of the Internet of things has promoted the rapid development of lead-free piezoelectric ceramics. The preparation method, piezoelectric property, application field and research progress of different ceramic systems on bismuth layer structure lead-free piezoelectric ceramics, tungsten bronze structure lead-free piezoelectric ceramics, perovskite structure lead-free piezoelectric ceramics（including sodium bismuth titanate Bi0.5Na0.5TiO3（BNT）, alkali niobate K0.5NaO5NbO3（KNN）, barium titanate BaTiO3（BT） piezoelectric ceramics） have been discussed in this paper. Finally, the future research on Piezoelectric ceramics has also been suggested.
