Sc2AlC
metal· Sc2AlC
Sc2AlC is a ternary carbide compound belonging to the MAX phase family of layered ceramics, which combines metallic and ceramic characteristics in a single material. This experimental material is primarily of research interest for aerospace and structural applications where its combination of damage tolerance, thermal stability, and electrical conductivity could provide advantages over conventional ceramics or monolithic metals. The MAX phase family is notable for retaining some plasticity and machinability despite ceramic-level stiffness, making materials like Sc2AlC candidates for high-temperature components where traditional brittle ceramics fail catastrophically.
