· Mn3Si

Mn₃Si is an intermetallic compound belonging to the manganese-silicon family, characterized by a defined crystal structure and metallic bonding. This material is primarily of research and specialized industrial interest, with applications in magnetic and structural applications where the unique electronic and magnetic properties of manganese intermetallics are leveraged. It is notable for its potential in permanent magnet systems, magnetic refrigeration, and high-temperature structural components, though it remains less commonly used than established alternatives like Ni-based superalloys or conventional ferrous intermetallics.
