Product Description

Industrial Grade CAS 7757-82-6 Sodium Sulphate 99% With Factory Price

Sodium sulfate (Na2SO4) is a salt formed by the combination of sulfate and sodium ions. Sodium sulfate dissolves in water and its aqueous solution is neutral. Soluble in glycerol but insoluble in ethanol. Exposure to air readily absorbs water to form sodium sulfate decahydrate. At 241 ° C sodium sulfate transforms into hexagonal crystals. Anhydrous sodium sulfate with high purity and fine particles is called sodium sulfate, and sodium sulfate decahydrate is commonly known as glauberite. Sodium sulfate tastes bitter and salty.

Application

1. Sodium sulfate is an important raw material for making glass and paper.
2. It is the largest in papermaking and cellulose industry, accounting for about 70% of the total.
3. Sodium sulfate is a component of synthetic detergent, it is a neutral salt, adding it can reduce the surface tension, increasethe solubility of detergent.
4. It is the diluent of dyes and the auxiliary agent of dyeing and printing.
5. In the chemical industry, sodium sulfate is used as raw material for the manufacture of sodium sulfide, gypsum, sodium silicate and other chemical products.
6. Mirabilite is used as a purgative in medicine. Sodium sulfate is an antidote to barium and lead poisoning.
