(Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 + 0.04 wt% CeO2 lead-free ceramics were synthesized by conventional sintering process and the effect of calcination temperature on microstructure, dielectric and piezoelectric properties were investigated. Improved piezoelectric properties have been observed at 1,125℃ calcination temperature which show the optimal electrical properties, kp∼0.457, d33∼367 pC/N, Qm∼158 and Tc∼85℃. These results show that the piezoelectric properties can be improved by appropriate calcination temperature.
