In this study, in order to develop composition ceramics for refrigeration device application, $Ba(Ti_{0.9}Zr_{0.1})O_3$ composition was fabricated using conventional solid-state method. Electrocaloric effect of this ceramic was investigated using the characteristics of P-E hysteresis loops at wide temperature range from room temperature to $150^{\circ}C$. Curie temperature of $Ba(Ti_{0.9}Zr_{0.1})O_3$ ceramics showed $80^{\circ}C$. The maximum value of ${\Delta}T=0.12^{\circ}C$ in ambient temperature of $115^{\circ}C$ under 30 kV/cm was appeared. It is concluded that $Ba(Ti_{0.9}Zr_{0.1})O_3$ ceramics can be applied as refrigeration device application.
