论文摘要
在过去的几十年中，基于电源效应对新的冷却技术产生了浓厚的兴趣。在聚合物和无机铁电材料中观察到的大型电局效应使新一代的介电冷却装置的开发成为可能。我们报告了退火对在12/65/35 PLZT散装陶瓷中观察到的电气效应的重要影响。通过直接测量获得电气数据。电气结果证实了该弛豫的铁电PLZT组成中存在明显的电位反应，超过了先前获得的钙钛矿弛豫铁电极中的电钙化值，例如PMN-PT和X/65/35 PLZT陶瓷。
Over the past decades, there has been significant interest in new cooling technology based on the electrocaloric effect. The large electrocaloric effect observed in polymeric and inorganic ferroelectric materials made possible development of dielectric cooling devices of a new generation. We report a significant impact of annealing on the electrocaloric effect observed in 12/65/35 PLZT bulk ceramics. The electrocaloric data were obtained by direct measurements. Electrocaloric results confirm the existence of the significant electrocaloric response in this relaxor ferroelectric PLZT composition exceeding previously obtained electrocaloric values in perovskite relaxor ferroelectrics such as PMN-PT and x/65/35 PLZT ceramics.
