摘要：

Well dispersed CeO2 nanoparticles are prepared by azeotropic co-precipitation method. (Ba0.96Ca0.04)(Ti0.30Sn0.10)O-3 lead-free piezoelectric ceramics doped with nano-CeOP2(x = 0 mol%, 0.03 mol%, and 0.07 mol%) and micro-CeO2(x = 0.03 mol%) are prepared at 1430 degrees C for 2 h by the conventional solid state sintering method. XRD diffraction indicates that all components have typical perovskite structure. Both doping of nano-CeO2 and micro-CeO2 can inhibit grain growth. And the average grain size decreased apparently with the increase of nano-CeO2 amount. All the samples exhibit typical diffuse phase transition behavior. The optimized electrical performances are obtained at x = 0.03 mol% with d(33) = 512 pC/N, k(p) = 41.5%, and P-r = 14.00 mu C/cm(2).
