Fluorite-type oxides exhibit outstanding properties,including high melting point,low thermal conductivity,and sintering resistance,making them one of the most extensively researched and highly promising high-entropy material structural systems.As the pyrochlore structure can be considered as an ordered defective fluorite structure,the paper categorizes it into the fluorite-type series.And high-entropy rare earth fluorite-type oxide structural systems at home and abroad can be divided into four categories:AO2-type,A2B2O7-type,A2B2O6O'-type,and biphasic RE2Zr2O7-type.The current research status of each structural system is comprehensively reviewed,and a future development of high-entropy rare earth fluo-rite-type oxides is discussed.
