摘要: 探讨了NiO掺杂量对PMS-PZ-PT三元系陶瓷的微观结构和电性能的影响.实验结果表明:随着掺杂量的增加,物相组成由四方相向三方相转变;NiO在PMS-PZ-PT材料中的固溶度比较小;当掺杂量为0.02wt%时,εr,d33,Qm等都有所提高,从而能获得好的压电性能,能满足超声马达实际使用的要求.

Abstract: The microstructure and piezoelectric properties of Pb0.98Sr0.02(Mn1/3 Sb2/3)x-(Zr0.5Ti0.5)1-xO3 ceramics were investigated systematically as a function of NiO-doping contents. Results show that, phases shift from tetragonal to rhombohedral phase with the increase of doping amounts, the solubility of NiO in PMS-PZ-PT ceramics is very small, and the composition with doping amount of 0.02wt% has superior piezoelectric properties. The modified compositions are practically suitable for ultrasonic motor (USM) applications.
