在综述Pb(Zr,Ti)O3(PZT)基反铁电材料的研制与性能研究进展的基础上,重点探讨了PZT95/5反铁电材料和在PZT基础上掺杂改性的Pb(Zr,Sn,Ti)O3(PZST),(Pb,La)(Zr,Sn,Ti)O3(PLZST)反铁电材料。总结了利用La3+、Nb4+、H f4+、Sr2+、Ba2+和Nd3+等离子对富锆PZT以及PZST粉体、陶瓷以及薄膜材料的掺杂取代改性研究。讨论了各类PZT基反铁电材料的铁电(FE)-反铁电(AFE)相变机理以及其场致应变性能。展望了PZT基反铁电材料今后研究与应用的发展方向。

The antiferroelectric materials based on lead zirconate titanate （PZT） are briefly reviewed. The typical anti-ferroelectric materials, PZT95/5, tin modified lead zirconate titanate （PZST） and its modifications, Lead lanthanum stannate zirconate titanate （PLZST） are summarized, respectively. High zirconium content PZT and PZST powders, ceramics and films doped by La^3 ＋ , Nb^4＋ , Hi^4＋ , Sr^2＋ , Ba^2＋ and Nd^3 ＋ are summed up, as well as their modification principles, preparation and properties. Based on these, the mechanisms and transition properties of ferroelectric （FE） to antiferroelectric （AFE） phase transitions in various of PZT-based antiferroelectric materials are discussed. Further aspects of research and future development about PZT-based antiferroelectric materials are proposed.
