· JVASP-40227· Ca2AsAu

Ca2AsAu is an intermetallic compound combining calcium, arsenic, and gold in a defined stoichiometric ratio. This material belongs to the family of ternary intermetallics and is primarily of research interest rather than established industrial production, with applications being explored in specialized electronics and materials science studies. The compound's potential relevance lies in niche applications requiring the unique combination of gold's chemical stability with the electronic properties of calcium-arsenic phases, though practical engineering use remains limited and typically confined to laboratory and theoretical investigations.
