Sodium sulfate is classified into three categories based on its industrial applications. Class I, the highest grade, is used in applications such as batteries, optical glass, printing and dyeing, synthetic detergents, vinyl, and fiber production. Class II is primarily used in industries like common glass, dyes, and paper manufacturing. Class III is mainly utilized in inorganic salt and other industrial raw materials.

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, increase the 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.
