چکیده انگلیسی
The microstructure and piezoelectric properties of the 0.01Pb(Mg1/2W1/2)O3-0.41Pb(Ni1/3Nb2/3)O3-0.35PbTiO3-0.23PbZrO3 + 0.1 and 0.3 wt.% Y2O3 + x ZnO ceramics were investigated. The crystal structure changed from psudocubic to tetragonal when ZnO added. The average grain size increased from 4 μm to 8 μm with the addition of ZnO by oxygen diffusion, even if the growth rate was low. When ZnO added until 0.5 wt.%, the ε33T/ε0, kp and d33 values of specimens were slightly increased regardless Y2O3 contents. The curie point of PMW-PNN-PT-PZ ceramics were increased from 162 °C to 232 °C, as increasing the ZnO contents. When ZnO added, the kp of specimens slightly was increased regardless Y2O3 contents. The mechanical quality factors were abruptly decreased regardless Y2O3 contents, when ZnO added until 0.75 wt.%. The optimized piezoelectric properties were obtained; d33 = 730 (pC/N), kp = 60, Qm = 50, and ε33T/ε0 = 4750, when PMW-PNN-PT-PZ + 0.3 wt.% Y2O3 + 0.5 wt.% ZnO sintered at 1200 °C for 1 h.
