Aluminum carbide (Al₄C₃) is an intermetallic ceramic compound formed from aluminum and carbon, belonging to the family of refractory carbides. It is primarily encountered as an unwanted byproduct in aluminum metallurgy and composites manufacturing, though it has potential applications in specialized high-temperature and wear-resistant contexts. The material is notable for its chemical reactivity—particularly its reaction with moisture—which makes it a research focus for understanding interfacial degradation in aluminum-carbon composite systems and for developing protective coating strategies.
