Multilayer ceramic electrocaloric material and preparation method thereof
The invention belongs to the field of electrocaloric refrigeration, and particularly relates to a multilayer ceramic electrocaloric material and a preparation method thereof, and the chemical composition of pre-sintered powder in MLCs is BaZrxTi (1-x) O3-Li2CO3; wherein 0.15 < = x < = 0.3, and 1% < = Li2CO3 < = 10%. The electrocaloric effect, the sintering temperature and the sintering compactness of the pre-sintered ceramic powder are jointly regulated and controlled mainly by changing the zirconium-titanium ratio and the content of the sintering aid. Based on the pre-sintered ceramic powder with the components regulated and controlled, the MLCs device is successfully prepared through a tape casting technology, and the MLCs device has the large electrocaloric effect and the low manufacturing cost.
本发明属于电卡制冷领域，具体涉及一种多层陶瓷电卡材料及其制备方法，该MLCs中预烧粉的化学组成为BaZrxTi1‑xO3‑Li2CO3；其中，0.15≤x≤0.3，1％≤Li2CO3≤10％。本发明主要通过改变锆钛比和烧结助剂的含量来共同调控预烧结瓷粉的电卡效应、烧结温度、烧结致密性。基于本发明调控成分后的预烧结瓷粉成功通过流延工艺制成了MLCs器件，该MLCs器件拥有大的电卡效应以及较低的制作成本。
