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