The effect of CeO2 as a sintering additive on the microstructure and the piezoelectric property of yPb(Sb0.5Nb0.5)O3-(1-y)Pb(Zr0.52Ti )O3 (0≤y≤0.1, PSN-PZT) for a hypersonic sound speaker (HSS) application was investigated. Thesamples were sintered at 1250oC for 2 h. The crystal structure and surface morphology of the samples were examinedusing XRD and FE-SEM, respectively. Study on the influence of CeO2 additives on the dielectric and piezoelectricproperties indicated that the CeO2-added PSN-PZT system had a high piezoelectric properties. The optimized results ofεr=1209, kp=52%, d 33=351(pC/N) and Qm=1230.16 were obtained at 0.4 wt.% CeO2-added PSN-PZT.
