natriumsulfatdecahydrat

natriumsulfatdihydrat is the hydrated form of sodium sulfate, a chemical compound with the formula Na2SO4·10H2O. It is also commonly known as Glauber's salt or Mirabilite. In its anhydrous form, it is simply sodium sulfate, Na2SO4. The dihydrate is a white crystalline solid that readily dissolves in water.

Historically, Glauber's salt was discovered by the German-Bohemian chemist Johann Rudolf Glauber in the 17th century. He obtained it from the residue left after evaporating mineral waters from a Hungarian spring. Its early uses included medicinal purposes, particularly as a laxative, though this application is less common today.

Industrially, sodium sulfate is a significant commodity chemical. Anhydrous sodium sulfate is produced in large quantities, primarily as a byproduct of chemical manufacturing processes such as the production of rayon and sodium dichromate. It also occurs naturally in large deposits, particularly in arid regions.

The primary uses of sodium sulfate include its role in the manufacturing of detergents, where it acts as a filler and helps with the solubility of other components. It is also used in the glass industry as a fining agent, helping to remove small bubbles from molten glass. Furthermore, it finds applications in the pulp and paper industry in the Kraft process for the production of wood pulp. In textile dyeing, sodium sulfate is employed to promote even dyeing. Natriumsulfatdihydrat itself is used in some niche applications, often related to its ability to absorb and release water, such as in phase-change materials for thermal energy storage.
