The research of high-entropy ceramics is still immature compared with high-entropy alloys

but a variety of high-entropy ceramics have been explored and prepared. High-entropy ceramic materials have unique structure and excellent properties

of which application prospect is very broad. Among them

the excellent phase stability

good matching with the thermal expansion coefficient of silicon-based ceramics

and excellent resistance to water vapor corrosion makes them very suitable for thermal barrier coatings

environmental barrier coatings and thermal/environmental barrier coatings. It has become a research hotspot of thermal protection coating in recent years. Based on the research on high-entropy ceramics in recent years

this article summarizes the current computer simulation methods

preparation processes and sintering processes used in the research of high-entropy ceramic materials

the application status and shortcomings of high entropy ceramic materials in thermal/environment barrier coatings are pointed out.
