KCu2As2
metal· JVASP-155642· KCu2As2
KCu₂As₂ is an intermetallic compound combining potassium, copper, and arsenic in a defined stoichiometric ratio. This is a research-phase material rather than a commercial engineering alloy; it belongs to the family of ternary metal arsenides that are primarily of scientific interest for their crystal structure, electronic properties, and phase behavior. Materials in this compound family have been investigated in condensed matter physics and materials chemistry for potential applications in thermoelectric devices, semiconductors, and fundamental studies of metal-metalloid interactions, though KCu₂As₂ itself remains primarily a laboratory curiosity without established industrial use.
