N2 - The piezoelectric ceramics xPb(Mn1/3Sb2/3)O3-(1-x) Pb(Zr1/2Ti1/2)O3 (abbreviated as PMS-PZT) were synthesized by traditional ceramics process. The effect of sintering temperature and the amount of Pb(Mn1/3Sb2/3)O3 (abbreviated as PMS) on phase structure, microstructure, piezoelectric and dielectric properties of PMS-PZT ceramics was investigated. The results show that the pure perovskite phase is in all ceramics specimens, the phase structure of PMS-PZT ceramics changes from tetragonal phase to single rhombohedral phase with the increasing amount of PMS. The dielectric constant εr, Curie temperature TC, electromechanical coupling factor kp and piezoelectric constant d33 decrease, whereas the mechanical quality factor Qm and dielectric loss tanδ increase with the increasing amount of PMS in system. The optimum sintering temperature is 1200-1250°C. It is concluded that the PMS-PZT (x=0.07) ceramics sintered at 1250°C is suitable for high-power piezoelectric transformer. These properties include εr=674.8, tanδ=0.00525, kp=0.658, Qm=1520, d33=230 pC/N, Tc=275°.
