· JVASP-118674· Mg2C

Mg₂C is an intermetallic ceramic compound belonging to the magnesium carbide family, characterized by a lightweight crystal structure with moderate elastic stiffness. This material is primarily of research and developmental interest rather than established in mainstream industrial production, with potential applications in lightweight composite reinforcement and high-temperature structural applications where magnesium-based ceramics offer advantages over heavier alternatives. Its notable attributes stem from the combination of low density with ceramic hardness, making it a candidate for aerospace and automotive applications where weight reduction is critical, though practical implementation remains limited due to synthesis challenges and competing established materials in these sectors.
