ZnO was added to 0.01Pb(Mg1/2W1/2)O 3-0.41Pb(Ni1/3Nb2/3)O3-0. 35PbTiO3-0.23PbZrO3 (0.01PMW-0.41PNN-0.35PT0.23PZ) ceramics to reduce their sintering temperatures to below 900°C. The effects of the ZnO additive on the densification and piezoelectric properties of the PMW-PNN-PT-PZ + 0.1 wt% Y2O3 + xwt% ZnO (0≤x≤2.5) ceramics were investigated. The structure of the PMW-PNN-PT-PZ ceramics was found to change from pseudocubic to tetragonal as their ZnO content was increased. The piezoelectric constant, the mechanical quality factor, and the electromechanical factor of the ceramics increased as their ZnO content increased. The optimum piezoelectric properties were found to be d33 = 594 pC/N, kp = 57%, and Qm = 64, for PMW-PNN-PT-PZ + 0.1 wt% Y2O3 4- 1.5 wt% ZnO sintered at 900°C for 2h.
