Abstract

采用传统工艺制备了PbZrO 3 -PbTiO 3 -Pb(Fe 2/3 W 1/3 )O 3 -Pb(Mn 1/3 Nb 2/3 )O 3 -BiFeO 3 (简称PZT-PFW-PMN-BF)四元系压电陶瓷. 研究了MnO 2 掺杂对PZT-PFW-PMN-BF陶瓷的显微结构、烧结温度、电性能与温度稳定性的影响. 结果表明, 当MnO 2 的掺杂量为0.10 wt%时, 陶瓷的烧结温度从1020℃降到了950℃, 并得到了较好的综合性能和温度特性, 分别为 d 33 =394 pC/N, K p =0.54, Q m =1180、 e r =1480, △ f r / f r25℃ =1.68 %和△ K p / K p25℃ =-1.06 %.
