Magnesium sulfide (MgS) is an inorganic ceramic compound belonging to the rock-salt structure family of binary ionic ceramics. It is primarily of interest in research and specialized optics applications rather than high-volume industrial production, valued for its wide optical transparency window extending into the infrared spectrum. MgS serves niche roles in infrared optics, thin-film coatings, and semiconductor research, where its combination of ionic bonding and wide bandgap makes it attractive for applications requiring thermal stability and optical clarity at longer wavelengths.
