摘要

采用常规固相反应法合成了Pb1-xSrx(Mn1/3Sb2/3)0.05Zr0.48Ti0.47O3+0.25%CeO2+0.50%Yb2O3+0.15%Fe2O3 (PMS-PZT, x=0, 0.02, 0.04, 0.06)的三元系硬性压电陶瓷。采用X线衍射仪、准静态压电常数测试仪和铁电测试仪系统地研究了Sr取代对PMS-PZT陶瓷的相结构及电学性能的影响。实验结果表明, 无Sr取代和有Sr取代的PMS-PZT压电陶瓷均具有单一的四方相晶体结构。当x=0.02时, PMS-PZT的性能最佳: d33=415 pC/N,Qm=522,TC=291 ℃,kp=0.64,εr=1 304,Pr=11.32 μC/cm2,Ec=9.05 kV/cm。

Abstract

The Pb1-xSrx(Mn1/3Sb2/3)0.05Zr0.48Ti0.47O3 +0.25%CeO2+0.50%Yb2O3+0.15%Fe2O3(PMS-PZT, x=0, 0.02, 0.04, 0.06) ternary system hard piezoelectric ceramics were synthesized by the conventional solid-state reaction method. The effects of Sr-substitution on the phase structure and electrical properties of the PMS-PZT ceramics were systematically studied by X-ray diffractometer, quasi-static piezoelectric constant tester and ferroelectric tester. The experimental results show that both the PMS-PZT piezoelectric ceramics with and without Sr-substitution have a single tetragonal crystal structure. When x=0.02, PMS-PZT has the best performance: d33=415 pC/N, Qm=522, TC=291 ℃, kp=0.64, εr=1 304, Pr=11.32 μC/cm2, Ec=9.05 kV/cm.
