· K3 Cu3 As2

K3Cu3As2 is an intermetallic compound combining potassium, copper, and arsenic in a fixed stoichiometric ratio. This material exists primarily in research and materials science literature rather than established industrial production, and represents a rare-earth-free alternative to conventional copper-based intermetallics. The compound belongs to the family of ternary metal arsenides, which are investigated for potential applications in thermoelectric systems, electronic devices, and catalysis due to their unique crystal structures and electronic properties, though practical engineering adoption remains limited and material availability is restricted to specialized synthesis.
