ReAcO3

ReAcO3 is a rare-earth-based ceramic oxide compound with a perovskite or perovskite-derived crystal structure, where Re represents a rare-earth element. This material family is primarily investigated for applications requiring high-temperature stability, ionic conductivity, or specific dielectric properties. ReAcO3 compounds are notably used in solid oxide fuel cells (SOFCs), oxygen-ion conductors, thermal barrier coatings, and catalytic applications, where their ability to maintain structural integrity and facilitate ion transport at elevated temperatures makes them competitive alternatives to yttria-stabilized zirconia and other conventional oxide ceramics.
