· ErFeC2

ErFeC2 is an intermetallic compound combining erbium (a rare-earth element), iron, and carbon. This material belongs to the family of rare-earth iron carbides, which are primarily of research and development interest rather than established commercial use. ErFeC2 and related rare-earth iron carbide systems are investigated for potential applications in permanent magnets, high-temperature structural materials, and specialty alloys where the combination of rare-earth elements with iron provides enhanced magnetic or mechanical properties; however, practical industrial deployment remains limited, making this a material of interest mainly to materials researchers and advanced applications engineering.
