Abstract

In this study, in order to develop composition ceramics for refrigeration device application, Ba(Ti_0.9Zr_0.1)O₃ 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℃. Curie temperature of Ba(Ti_0.9Zr_0.1)O₃ ceramics showed 80℃. The maximum value of ?T = 0.12℃ in ambient temperature of 115℃ under 30 kV/cm was appeared. It is concluded that Ba(Ti_0.9Zr_0.1)O₃ ceramics can be applied as refrigeration device application.
