Research progress and prospect of high entropy oxide

Abstract

High entropy oxide ceramics are stable solid solutions with single-phase structure, which are synthesized from five or more oxides with equal molar ratio and have excellent thermal, magnetic, electrical and corrosion resistance properties. At present, the researches mainly focus on the in-depth exploration and expansion of the existing properties of high entropy oxide ceramics, as well as their applications based on its excellent properties in lithium ion battery electrode materials, dielectric materials, magnetic materials and catalytic materials, etc. In this paper, the classification, the preparation methods and the properties of high entropy oxide ceramics are reviewed, and the development direction of high entropy oxide ceramics is analyzed and prospected.
