摘要
研究了Ｐｂ（Ｃｄ１／３Ｎｂ２／３）Ｏ３、Ｂｉ２／３（Ｃｄ１／３Ｎｂ２／３）Ｏ３以及Ｂｉ（Ｃｄ１／２Ｔｉ１／２）Ｏ３改性的ＰｂＴｉＯ３陶瓷的高温高频压电性能。结果表明，对ＡＢＯ３型钙钛矿结构的ＰｂＴｉＯ３进行Ａ、Ｂ位复合取代可得到压电性能优良，适合于高温高频应用的压电陶瓷材料。其优良的压电性能及较好的温度稳定性与Ａ位取代的Ｂｉ３＋离子价态。
The piezoelectric properties of PbTiO 3 ceramics modified with Pb(Cd 1/3 Nb 2/3 )O 3,Bi 2/3 (Cd 1/3 Nb 2/3 )O 3 and Bi(Cd 1/2 Ti 1/2 )O 3 were investigated.The experimental results indicate that the ceramic materials with excellent piezoelectric properties for high temperature and high frequency applications can be obtained by complex substitutions of the A and B sites for PbTiO 3 ceramics with ABO 3 perovskite structure.The excellent properties and better temperature stabilities result from the ionic valence and the ionic radius of Bi 3+ in the A site as well as the high Curie temperature of the complex perovskite composition with B site substitution.
