Abstract

$(Ba_{0.85}Ca_{0.15})(Ti_{0.9}Zr_{0.1})O_3$ + 0.04 wt% $CeO_2$ 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 $1,125^{\circ}C$ calcination temperature which show the optimal electrical properties, $k_p$~0.457, $d_{33}$~367 pC/N, $Q_m$~158 and $T_c$~$85^{\circ}C$. These results show that the piezoelectric properties can be improved by appropriate calcination temperature.
