Magnesium sulfide is a chemical compound selected from the group of the sulfides. It is in the form of a reddish to reddish brown powder. Chemically pure MgS is colorless.

Occurrence

Of course, magnesium sulfide occurs as part of the detected in meteorites Minerals Niningerit.

Production and representation

Magnesium sulfide may be obtained by reaction of sulfur and hydrogen sulfide with magnesium.

Also possible is the production of magnesium sulfate by carbon disulfide method of Tiede and judges,

And by passing hydrogen sulfide over Ammoniumcarnallit.

Properties

The crystal structure of magnesium sulfide oktaedral and corresponds to that of sodium chloride.

On contact with water or moisture hydrolysed magnesium sulfide, magnesium hydroxide and magnesium hydrogen sulfide occur:

Use

Magnesium sulfide is used in cosmetics as a depilatory. With cerium and samarium doped magnesium sulfide luminesce when irradiated with UV light after optical stimulation and is therefore used as a dosimeter.
