Classification, Properties and Applications of High Entropy Ceramics

High-entropy ceramics have garnered growing attention in recent years, primarily due to their outstanding performance under extreme conditions. First formally proposed and defined in 2004, the study of high-entropy ceramics has since seen significant advancements. Through continuous research efforts, a diverse range of high-entropy ceramics has been successfully synthesized, each demonstrating distinct performance characteristics. To facilitate researchers' quick understanding and further study of high-entropy ceramics, this paper reviews the research progress of high-entropy ceramics from the perspectives of their classification and properties.
