· JVASP-120334· Mg2Se

Mg₂Se is an inorganic ceramic compound belonging to the magnesium chalcogenide family, combining magnesium metal with selenium in a 2:1 stoichiometric ratio. This material is primarily of research and developmental interest rather than established in high-volume industrial production; it is studied for potential applications in optoelectronics, semiconductor devices, and thermal management systems where its wide bandgap and crystal structure offer theoretical advantages. Compared to more common alternatives like MgO or commercial III-V semiconductors, Mg₂Se remains in the exploratory phase but represents part of a broader materials class being investigated for infrared optics, photovoltaic devices, and specialized high-temperature environments where lightweight ceramics with moderate stiffness are beneficial.
