Research Progress of High-Entropy Ceramic Materials

Abstract

The concept of high-entropy alloy not only greatly enriches the metal material system，but also breaks the design routine of traditional ceramic material.In recent years，people are gradually extending the design concept of multi-principal and high-entropy to ceramic materials，and a series of multi-principal high-entropy ceramics have been fabricated.Thanks to its unique structure and “four effects”similar to high-entropy alloy，high-entropy ceramics exhibit a series of excellent mechanical，thermal and tribological properties.Based on the preparation methods，structural characteristics and properties，this article mainly introduced the research progress of high-entropy oxide，carbide，nitride ceramics and other high-entropy carbonitrides，borides，silicides and sulfides at home and abroad，and analyzed the specific structures and properties of those high-entropy ceramics.Finally，the development prospect of the high-entropy ceramic was also prospected.
