· JVASP-8682· AuCN

AuCN is an intermetallic compound combining gold and carbon-nitrogen phases, representing an emerging material in the intersection of precious metals and light-element compounds. While not yet widely commercialized, this material is primarily of research interest for applications requiring the corrosion resistance and electronic properties of gold combined with enhanced mechanical characteristics from carbon-nitrogen bonding. Its potential relevance spans advanced coatings, nanoelectronic contacts, and specialized aerospace or chemical-processing applications where gold's inertness must be combined with improved mechanical performance or reduced material consumption.
