Dielectric and Piezoelectric Properties of (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3Ceramics as a Function of Sintering Temperature

(Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 + 0.04 wt% CeO2 lead-free ceramics were prepared by conventional oxide-mixed method and the effect of sintering temperature on microstructure, dielectric and piezoelectric properties were investigated. Improved piezoelectric properties have been observed at 1,400°C sintering temperature which show the optimal electrical properties, kp∼0.412, d33∼316 pC/N, Qm∼144, er∼3,345 and Tc∼85°C. These results show that the sintering temperature plays an important role in piezoelectric properties.
