· JVASP-9946· Ca2YSnO5

Ca₂YSnO₅ is a rare-earth-containing oxide ceramic compound combining calcium, yttrium, and tin oxides. This material is primarily of research interest for high-temperature applications and advanced ceramics, particularly in contexts requiring thermal stability and chemical resistance in oxidizing environments. It represents an emerging composition in the pyrochlore and perovskite-related ceramic family, with potential applications in thermal barrier coatings, refractories, and solid-state electronics where rare-earth doping provides functional properties unavailable in conventional oxides.
