GdScO3

Gadolinium scandate (GdScO3) is a perovskite ceramic compound combining rare-earth gadolinium with scandium oxide, primarily investigated as a high-performance electrolyte and substrate material for solid-state energy devices. It is employed in solid oxide fuel cells (SOFCs), oxygen sensors, and as a single-crystal substrate for epitaxial growth of functional oxide thin films, particularly valued for its ionic conductivity at elevated temperatures and structural compatibility with advanced ceramic coatings. While largely a research and development material rather than commodity, GdScO3 represents the broader class of rare-earth perovskites being engineered to replace yttria-stabilized zirconia (YSZ) in demanding thermal and electrochemical applications.
