How Is Sodium Sulfate Used In Industry?

Sodium sulfate has several industrial uses, including:

1. Detergent manufacturing: Sodium sulfate is used as a filler in powdered detergents to increase their bulk and improve their flow properties.

2. Glass manufacturing: Sodium sulfate is added to the mixture of raw materials used to make glass to lower its melting point and improve its workability.

3. Pulp and paper production: Sodium sulfate is used as a cooking chemical in the production of wood pulp for papermaking, helping to break down the fibers and separate the cellulose from the lignin.

4. Textile dyeing: Sodium sulfate is used as a leveling agent in textile dyeing, helping to ensure that the dye is evenly distributed across the fabric.

5. Chemical synthesis: Sodium sulfate is used as a source of sulfur in the production of various chemicals, such as sodium sulfide and sodium bisulfite.

Overall, sodium sulfate is a versatile compound with a wide range of industrial applications.
