| Abstract: | 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 ),Hf~(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. |
