Perovskite Pb(Mn_{1/3}Sbu_{2/3})O_2-Pb(Zr,Ti)O_3\;(PMS-PZT) was prepared and ZnO doping effects on its piezoelectric properties were investigated. Pyrochlore phase was not identified in the PMS-PZT ceramics with 0∼5mol% ZnO sintered at 1100 ? C for 2 hrs, and maximum sintered density of 7.92g/cm 3 was obtained. Piezoelectric charge constant and voltage constant increased to 359×10 ?12 C/Nand22.5×10 ?13 Vm/N , respectively, with increasing ZnO content. Mechanical quality factor reduced considerably with increasing ZnO content. When the ZnO content was 3 mol% , electromechanical coupling factor and relative dielectric constant showed maximum values of 56% and 1727, respectively. This should be evaluated by complicated variations of sintered density, tetragonality of lattice, grain size, and A-site vacancy generated by ZnO addition and Zn 2+ substitution.

Keywords:PMS-PZT;piezoelectric;ZnO doping
