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.
The industrial anhydrous sodium sulfate appears as white crystalline granules.
