· CaAu2

CaAu2 is an intermetallic compound combining calcium and gold in a 1:2 stoichiometric ratio, belonging to the family of gold-based intermetallics. This material is primarily of research and academic interest rather than established industrial production, with potential applications in specialized areas where the unique combination of gold's chemical stability and calcium's lightweight characteristics might offer advantages. The compound's notable elastic properties and high density make it relevant for theoretical materials science studies and emerging technologies in electronics, catalysis, or specialized coatings where gold-intermetallic phases are being explored.
