摘　　要：用固相反应法制备了掺杂WO3的PMS-PNN-PZT压电陶瓷,研究了WO3对PMS-PNN-PZT陶瓷的相结构与压电性能的影响。WO3的加入促进了PMS-PNN-PZT压电陶瓷的烧结致密化。掺杂0.5wt%时,在1100℃下烧结具有最佳压电性能:d33=381p C.N-1,Qm=1040,Kp=0.53,rε=1448,tanδ=0.0052。The effect of WO3 doping on phase structure and piezoelectric properities of PMS.PNN-- PZT piezoelectric ceramics prepared by using solid phase reaction was investigated. The ceramics will become densification after sintering because of the addition of WO3. The composition with w（WO3） of 0.5% has better properties when the samples are sintered in the condition of 1100℃ ~ d33 =381pC · N^-1 ,Qm = 1040,Kp=0.53,εr= 1448,tanδ=0. 00520
