· JVASP-120336· MgSe2

MgSe₂ is an inorganic ceramic compound belonging to the magnesium chalcogenide family, combining magnesium with selenium in a layered crystal structure. This material is primarily of research and developmental interest rather than established commercial use, with potential applications in optoelectronic devices, thermal management systems, and solid-state physics where its unique electronic and thermal properties could be leveraged. MgSe₂ represents an emerging candidate for niche applications in semiconducting ceramics and advanced materials research, though industrial adoption remains limited compared to more mature ceramic alternatives.
