How Is Magnesium Sulphide Prepared?

Magnesium sulphide can be prepared by heating magnesium and sulphur in a vacuum or in an inert atmosphere, such as argon. The reaction between the two elements produces magnesium sulphide according to the following equation:

Mg + S → MgS

The resulting product is a white crystalline solid with a melting point of approximately 2,083°C (3,781°F). Magnesium sulphide is insoluble in water and has a wide range of applications in the fields of semiconductors and electronics, as well as in the production of magnesium metal.
