Magnesiumsulfid

synthetischeMagnesium Sulfide can be prepared by the direct reaction of the elements, calcined in an inert atmosphere, at a 1:1.1 molecular ratio: Mg＋ S＋ heat→MgS MgS also forms by the reaction of hydrogen sulfide gas with soluble magnesium salts in solution. Aside from being a component of some slags, MgS is a rare nonterrestial mineral “niningerite” detected in some meteorites. Magnesium sulfide is available commercially from a number of suppliers.
