摘要
通过对PSN-PZT系统PSN的含量和Zr/Ti比值的调整,使系统点处于准同型相界附近时性能可以得到优化,这一点从微观结构分析得到验证。通过引入Sr^(2+)、Nb^(5+)和Mn^(2+)等离子,对系统进行A位和B位掺杂取代来提高其性能,获得了性能优异的压电陶瓷材料,其d_(33)·g_(33)最大值可达16030×10^(-15)CVm/N^2,适于用作收发兼用的换能器材料。
Effects of the compositions of PSN-PZT system on the piezoelectric properties and their mechanisms were studied. By adjusting the mole percent of PSN and the ratio of Zr/Ti, the system point could be located near to the morphotropic phase boundary when the properties could be optimized. The result had also been proved by the microstructural analysis. By means of doping the additive ions such as Sr^2＋, Nb^5＋ and Mn^2＋ to substitute for the A- and B- sites of the perovskite structure, the performances of the system could be further improved, and an excellent piezoelectric ceramic material was obtained. Its maximum d33·g33 could be enhanced to 16030×10-15CVm/N2, and this material is proper to be used in receiving and projecting dual-purpose transducer.
