摘要
本文对ＰＺＮ－ＰＮＮ－ＰＺＴ四元系统压电陶瓷组成与性能的关系进行了研究。通过Ｃａ、Ｓｒ、Ｂａ等元素对部分Ｐｂ的置换以及用Ｌｉ２ＣＯ３、Ｓｂ２Ｏ３等适当地掺杂改性，可获得介电常数ε３３／ε０～７０００、ｄ３３～８００ｐｃ／Ｎ、Ｋｐ～０．６５的一系列高性能压电陶瓷。
In this article,the relation of properties with composition of PZN-PNN-PZT system piezoelectric Ceramics is studied.A series of piezoelectric ceramics with high property (exp.33/07000,d33800 pc/N,Kp0.65) can be made by replacing Pb with elements Sr,Ca and Ba and by properly dopping with Li2CO3 and Sb2O3.These materials are used for making ultrasonic motors and high grade electroacoustic elements.
