· JVASP-8084· KCuC2

KCuC2 is an intermetallic compound combining potassium, copper, and carbon, representing an experimental phase in the copper-carbon system with potential applications in advanced materials research. This material belongs to the family of copper carbides and intermetallics, which are being studied for their unique mechanical and electronic properties. While not yet widely deployed in mainstream engineering, copper-carbon intermetallics are of interest in materials science for exploring novel combinations of strength, electrical conductivity, and thermal properties that diverge from conventional alloys.
