High-efficiency high-energy-storage sodium niobate-based ceramic material and preparation method thereof

CHEN XIULI / DONG XIAOYAN / ZHOU HUANFU / ZHANG HAILIN / DENG LIAN

The invention relates to the technical field of dielectric ceramic materials, and particularly discloses a high-efficiency high-energy-storage sodium niobate-based ceramic material and a preparation method thereof. The chemical composition formula of the material is (1-x)[0.9NaNbO3-0.1Bi(Mg0.667Nb0.333)O3]-xmol%(Bi0.5Na0.5)0.7Sr0.3TiO3 (x is larger than or equal to 0.05 and smaller than or equal to 0.4), wet ball milling is carried out by adopting a solid-phase reaction method and taking an ethanol solution as a ball milling medium, and raw powder uniform in particle size is obtained. The high-performance energy storage ceramic is prepared by adopting a traditional sintering process.

本发明涉及电介质陶瓷材料技术领域，具体公开了一种高效高储能铌酸钠基陶瓷材料及其制备方法，该材料的化学组成式为：(1‑x)[0.9NaNbO3‑0.1Bi(Mg0.667Nb0.333)O3]‑xmol％(Bi0.5Na0.5)0.7Sr0.3TiO3(0.05≤x≤0.4)，通过采用固相反应法，以乙醇溶液为球磨介质进行湿法球磨，获得粒径均匀原粉；采用传统烧结工艺，制备出高性能储能陶瓷。
