Agricultural use:

Sodium sulfate is used to make sodium sulfide, paper pulp, glass, water glass, enamel, and also used as a laxative and antidote for barium salt poisoning. It is a by-product of the production of hydrochloric acid from table salt and sulfuric acid. Chemically used to make sodium sulfide, sodium silicate, etc. The laboratory is used to wash away the barium salt.

The role and use of sodium sulfate
1. Used in the chemical industry to manufacture sodium sulfide sodium silicate water glass and other chemical products.
2. In the paper industry, it is used as a cooking agent in the manufacture of sulphate pulp.
3. In the glass industry, it is used as a co-solvent instead of soda ash.
4. In the textile industry, it is used to formulate vinylon spinning coagulant.
5. Used in non-ferrous metal metallurgy, leather, etc.
6. Used to make sodium sulfide, paper pulp, glass, water glass, enamel, and also used as a laxative and antidote for barium salt poisoning. It is a by-product of the production of hydrochloric acid from table salt and sulfuric acid. Chemically used to make sodium sulfide, sodium silicate, etc. The laboratory is used to wash away the barium salt. Industrially used as raw materials for preparing NaOH and H?SO?, and also used in papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc. Sodium sulfate is the most commonly used post-treatment desiccant in organic synthesis laboratories.
7. Mainly used as a filler for synthetic detergents. The paper industry is used as a cooking agent in the manufacture of kraft pulp. The glass industry is used to replace soda ash. The chemical industry is used as a raw material for the manufacture of sodium sulfide, sodium silicate and other chemical products. The textile industry is used to prepare vinylon spinning coagulation bath. Used as a laxative in the pharmaceutical industry. It is also used in non-ferrous metallurgy and leather.
8. The hydration product calcium sulfoaluminate is produced faster, thereby accelerating the hydration and hardening speed of cement. The content of sodium sulfate is generally 0.5% to 2% of the cement quality, which can increase the early strength of concrete by 50% to 100%. The 28-day strength sometimes increases, sometimes decreases, and the increase rate is about 10%, depending on the type of cement and curing conditions. And its content varies. It is also used as a filler for synthetic detergents, and is also used in the paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.
9. Used as an analytical reagent, such as a dehydrating agent, a digestion catalyst for nitrogen determination, and an interference inhibitor in atomic absorption spectroscopy. It is also used in the pharmaceutical industry.
10. Used in the chemical, paper and glass, dye, printing and dyeing and pharmaceutical industries. It is also used in the manufacture of synthetic fibers, leather, non-ferrous metallurgy, enamel, etc. It is also used as an additive in detergents and soaps.
11. It can be used as a buffer in sulfate zinc plating to stabilize the ph value of the plating solution.

Mainly used as a filler for dyes and auxiliaries to adjust the concentration of dyes and auxiliaries to achieve standard concentrations.
It can also be used as an accelerator for direct dyes, sulfur dyes, and vat dyes when dyeing cotton, and as a retarding agent for direct acid dyes when dyeing silk and wool animal fibers.
It can also be used as a base color protectant in the refining of printed silk fabrics.
The paper industry is used as a cooking agent in the manufacture of kraft pulp.
The pharmaceutical industry is used as an antidote for barium salt poisoning.
In addition, it is also used in the glass and construction industry.
