MnS
metal· MnS
Manganese sulfide (MnS) is an inorganic ceramic compound belonging to the rock salt family of transition metal chalcogenides, characterized by strong ionic bonding between Mn²⁺ and S²⁻ ions. It appears primarily in metallurgical applications as a desulfurizer and inclusion modifier in steel production, where it reduces brittleness by controlling sulfide morphology during casting. MnS is also investigated in semiconductor and thermoelectric research due to its narrow bandgap properties, making it relevant for emerging applications in optoelectronics and solid-state energy conversion, though commercial use remains concentrated in iron and steel manufacturing.
