Magnesium Sulfide Melting Point

The melting point of magnesium sulfide is approximately 2,282°C or 4,140°F. This value may vary slightly depending on the purity and preparation of the compound. Magnesium sulfide is a white to yellowish crystalline solid with a chemical formula of MgS. It is insoluble in water and has a high melting point due to its strong ionic bonds between the magnesium and sulfur ions. Magnesium sulfide is primarily used in the production of ceramics and as a source of sulfur for chemical reactions.
