· CsCaH3

CsCaH3 is a ternary metal hydride ceramic compound combining cesium, calcium, and hydrogen. This material belongs to the family of complex hydrides and is primarily of research interest rather than established industrial production, with potential applications in hydrogen storage and advanced ceramic technologies where high hydrogen density and stability are relevant.
