Anhydrous magnesium sulfate is a magnesium containing compound with the molecular formula MgSO4. Anhydrous magnesium sulfate is a common chemical reagent and drying reagent. However, magnesium sulfate often refers to magnesium sulfate heptahydrate, because it is not easy to deliquesce and is easier to weigh than anhydrous magnesium sulfate, which is convenient for quantitative control in industry.

It has a role as an antimetabolite, an antineoplastic agent, an immunosuppressive agent, an antiviral agent, a prodrug and a DNA synthesis inhibitor.

Veterinary antibiotics are used for bacterial diseases of pigs, chickens and fish caused by sensitive bacteria, especially for respiratory infection and intestinal infection.

It is mainly used as water purifying agent for drinking water and precipitant for wastewater treatment and purification. The printing and dyeing industry is used as oxidant and mordant in indigo dyeing. Catalyst for organic synthesis of dichloroethane and other production. Chlorinated extractant for silver and copper ore. An etchant for photographic and printing plate making. Raw materials for manufacturing iron salts such as iron phosphate, medicine, pigment and ink. After infiltrating its solution into the building concrete, it can increase the building strength, corrosion resistance and prevent water seepage. It is used in the production of circuit board and fluorescent digital tube in electronic industry. Coagulant for recovering glycerol from waste liquid of soap production.

Sodium sulfate is an important chemical raw material. It is the main raw material for the production of sodium sulfide, sodium silicate and other chemical products. It can also be used as a filler for synthetic detergent and a cooking agent for the manufacture of sulfate pulp in the paper industry. Sodium sulfate is also called sodium sulfate, anhydrous mirabilite and anhydrous tannite. White monoclinic fine crystal or powder. The relative density is 2.68 and the melting point is 884 ℃. Soluble in water, the aqueous solution is neutral. Soluble in glycerine oil, insoluble in ethanol, exposed to air, easy to absorb water and become aqueous sodium sulfate. It is a homogeneous polycrystalline substance, which is rhombic at 32.4 ~ 223 ℃, monoclinic crystal at higher temperature, and hexagonal crystal at 241 ℃. When crystallized from solution, it has affinity for iron, iron compounds and various organic substances; Anhydrous sodium sulfate with high purity and fine particles is called sodium sulfate.
