초록

In this work, in order to develop the ceramics with an excellent electrocaloric effect, $[Bi_{0.5}(Na_{0.84}K_{0.16})_{0.5}]TiO_3$ ceramics were fabricated by conventional solid state reaction method. The ceramics was observed as rhombohedral phase by X-ray diffraction patterns. To investigate the electrocaloric effect of the ceramics, P-E hysteresis loops were measured at various temperature. The temperature change ${\Delta}T$ of these ceramics was calculated using the Maxwell's relations. The maximum value of temperature change ${\Delta}T$ was obtained as 0.3 $1^{\circ}C$ at $165^{\circ}C$ under applied electric fields 45 kV/cm.
