High-entropy perovskite ceramics: Advances in structure and properties

High -entropy ceramic materials usually refer to the multi -principal solid solution formed by 5 or more ceramic components. Due to its novel "high -entropy effect" and excellent performance, it has become one of the research hotspots in the field of ceramics in recent years. As the research system of high -entropy ceramics has gradually expanded from the initial rock salt oxides (Mg-Ni-Co-Cu-Zn)O to fluorite oxides, perovskite oxides, spinel oxides, borides, carbides and silicates, its special mechanical, electrical, magnetic and energy storage properties have been continuously discovered. Based on the basic principle of high -entropy materials, this paper mainly introduces the prominent perovskite-type oxide high -entropy ceramics in recent years from the perspective of ceramic structure and properties, and predicts the development trend of high -entropy perovskite-type ceramics in the next few years.
