· JVASP-87080· KCu4As2

KCu4As2 is an intermetallic compound containing copper and arsenic with potassium as a constituent element, representing a specialized metal system outside conventional engineering alloys. This material is primarily of research interest rather than established industrial use, with investigation focused on understanding its crystalline structure, electronic properties, and potential role in advanced materials science. Its notable density and composition suggest possible applications in specialized electronic, catalytic, or materials research contexts, though practical engineering adoption remains limited compared to conventional copper alloys or arsenic-containing semiconductors.
