In recent years,high-entropy alloys have developed many systems,and some of them have been applied.High-entropy ceramics is another important breakthrough of high-entropy concept after high-entropy alloy,it has developed steadily.High-entropy ceramics usually refer to multi-principal components solid solution formed by five or more ceramic components,and perform excellent mechanical,thermal,electrical and magnetic properties,which is of great application value.This review described the high-entropy ceramics research progress at home and abroad,and look forward to the future development.
