· JVASP-63271· KAuC2N2

KAuC₂N₂ is an intermetallic compound containing potassium, gold, carbon, and nitrogen—a rare quaternary phase that exists primarily in research and materials science literature rather than established industrial production. This material belongs to an experimental family of multi-element compounds being investigated for potential functional applications in advanced materials, though mainstream engineering use is currently limited. Engineers would encounter this compound primarily in specialized research contexts exploring novel material combinations or in theoretical materials databases rather than in conventional design and manufacturing.
