PZT 掺杂改性研究进展及其机理探究

摘要

As one of a typical perovskite structure.PZT provide a wide flexibility for doping modification.The paper have introduced the current investigation of PZT-doping modification and briefly analyzed the variation of property which affected by equivalent doping,donor doping,acceptor doping and multiple doping respectively The theory of doping modification has been discussed by two aspects:crystal structure and domain structure effected by doping,which will provide theoretical base of doping.%PZT 作为典型的钙钛矿结构，该结构为掺杂改性提供了较大的自由度。介绍了 PZT 压电材料掺杂改性的研究现状，简明扼要的分析了等价掺杂、高价掺杂、低价掺杂以及复合掺杂对压电材料各项性能的影响。并从掺杂离子对晶体结构和电畴结构影响两方面探讨了 PZT 掺杂改性的机理，进而为复合掺杂改性提供理论基础。
