What Are The Physical Properties Of Magnesium Sulfide?

Magnesium sulfide is a chemical compound with the formula MgS. It is a white or yellowish crystalline solid that has a high melting point of 2,082 °C and a boiling point of 1,832 °C.

Magnesium sulfide is insoluble in water and most organic solvents, but it can react with acids to produce hydrogen sulfide gas. It has a density of 2.71 g/cm3 and a molar mass of 56.38 g/mol. Magnesium sulfide is a semiconductor with a band gap of approximately 3.6 eV.

In terms of its crystal structure, magnesium sulfide adopts the sodium chloride structure, where each magnesium cation is surrounded by six sulfide anions and each sulfide anion is surrounded by six magnesium cations.

Magnesium sulfide has a wide range of applications, including in the production of semiconductors, electronics, and optoelectronics. It is also used as a catalyst and as a desulfurizing agent in the petroleum industry.
