Abstract: High-entropy materials represented by high-entropy alloys have been the focus of materials science research in the past 15 years. In contrast to rapid and fruitful progresses in high-entropy alloys, studies on high-entropy ceramics are still in the infant stage. To date, considerable progress has been made in exploring new high-entropy ceramic systems and in their composition-structure-performance relationship. This article summarizes and reviews the connotation, new system, application and development direction of high entropy ceramics.
Key words: high-entropy ceramics; entropy-stabilized ceramics; high-entropy alloys; solid solution
