· JVASP-19093· CaSc2O4

Calcium scandium oxide (CaSc₂O₄) is an inorganic ceramic compound belonging to the rare-earth oxide family, characterized by a mixed-valence crystal structure. This material is primarily of research interest in solid-state chemistry and materials science, with potential applications in optical devices, thermal barrier coatings, and advanced ceramics where scandium-doping of calcium compounds offers improved refractory properties and thermal stability compared to undoped calcium oxides.
