Dielectric Properties and Electrocaloric Effects of PLZT Ferroelectric Ceramics by Applying Electric Fields Kim, You-Seok; Yoo, Ju-Hyun; Jeong, Yeong-Ho;
In this study, in order to develop relaxor ferroelectric ceramics for refrigeration device application with large electrocaloric effect, PLZT(8/65/35) composition was fabricated using conventional solid-state method. The Curi temperature of this composition PLZT ceramics was , and the P-E hysteresis loops of the PLZT ceramics as a fuction of temperature became slim by degrees with higher temperatures. The maximum value of of in ambient temperature of with 30 kV/cm was appeared. It is considered that PLZT ceramics possess the possibility of refrigeration device application.
