The electrocaloric effect in 0.94(Bi0.5Na0.5)TiO3+0.06KNbO3+0.9 wt% G.F.ferroelectricceramics was observed in terms of the temperature change (ΔT) of the fabricated ceramics, Curie temperature Tc, and applied electric field. The specimens were fabricated by a conventional solid-state reaction. Tc appeared near 165∼170℃. The P-E hysteresis showed a tendency to slim down with a temperature increase and finally was slimmest near 150℃. With the increase of temperature, the polarization revealed a gradual decrease, and a sharp decline near Tc. When an electric field of 45 kV/cm was applied, the largest polarization was shown. The maximum value of the temperature change (ΔT=0.31℃) was obtained at 165℃ under an applied electric field of 45 kV/cm.
