Sulfate of magnesium represents colourless hygroscopic crystals with a rhombic lattice, soluble in water, ethanol, glycerin and ethyl oxide. Have the expressed bitter taste. Disappear on air. Forms crystalline hydrates with water molecules. Is inorganic substance, salt of metal of magnesium and sulfuric acid.

Density is 2,66 g/cm ³. Melting temperature: 1137 °C.

Chemical formula: MgSO4

Sulfate of magnesium is received interaction of sulfuric acid with oxide, hydroxide and a carbonate of magnesium, also in the industry it is received from sea water, minerals of epsomite, a kizerit or carnallite.

In chemical industry it is applied in technological processes of receiving sulfuric acid and oxide of magnesium, by production of synthetic detergents as the stabilizer of perekisny connections.
In agriculture sulfate of magnesium is used as effective magnesian sulfur-containing fertilizer of the soil under crops. Increases productivity, improves tastes of potatoes, vegetables due to increase in contents in fruits of starch and vitamins.
