Abstract
The piezoelectric ceramic Pb0.94Sr0.06(Zr0.53Ti0.47)O3 + 0.1 wt% (Ni2O3 + Cr2O3) + x wt%CeO2 (PCrNi-4) was prepared using a traditional solid state sintered method. The effects of CeO2 doping on phase structure, microstructure, piezoelectric, and dielectric properties were analyzed by means of XRD, SEM, and electrical property measurements. The results indicate that when CeO2 doping content is 0.3 wt% and sintering temperature is 1,280 °C, the dielectric loss value of the ceramic is the least with a value of 0.00238, and the dielectric factor $$ \varepsilon_{33}^{\text{T}} $$ , piezoelectric strain factor d 33, planar electromechanical coupling coefficient K p and mechanical quality factor Q m of the ceramic is 1400, 375 pCN−1, 0.68, and 460, respectively.
