· BaAu2

BaAu₂ is an intermetallic compound combining barium and gold, belonging to the class of binary metallic compounds with ordered crystal structures. This material is primarily of research interest rather than established industrial production, studied for its potential in high-performance applications where the combination of a reactive alkaline-earth metal with noble metal properties could offer unique electronic or structural characteristics. Interest in BaAu₂ and similar barium-gold phases centers on fundamental metallurgy, potential thermoelectric or electronic device applications, and as a model system for understanding intermetallic phase behavior and stability.
