Abstract
$(Ba_{0.85}Ca_{0.15})(Ti_{0.9}Zr_{0.1})O_3$ + 0.04 wt% $CeO_2$ 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 $1,400^{\circ}C$ sintering temperature which show the optimal electrical properties, $k_p{\sim}0.412$, $d_{33}{\sim}316pC/N$, $Q_m{\sim}144$, ${\varepsilon}_r{\sim}3,345$ and $T_c{\sim}85^{\circ}C$. These results show that the sintering temperature plays an important role in piezoelectric properties.
