Sodium sulphate and its applications
Sodium sulphate forms colourless, water soluble crystals and can be found in nature as Thenardit. The decahydrate of sodium sulphate is well-known as Glaubers´s salt which crystallises from water and is used for already a long time as laxative. Water-free sodium sulphate is not a typical chlor-alkali product but a by-product from the brine purification in Bitterfeld.
