Sodium Sulphate Anhydrous/ Glauber Salt/ Yuanming Powder/ Sodium Sulphate Na2SO4
Sodium sulfate is a salt formed by the combination of sulfate and sodium ions. Its chemical formula is Na2SO4. Sodium sulfate is soluble in water. Most of its solutions are neutral, soluble in glycerin but not in ethanol. Inorganic compounds, high-purity, fine-grained anhydrous substances are called sodium sulfate. Yuanming powder, white, odorless, bitter crystal or powder, with hygroscopicity. The appearance is colorless, transparent, large crystals or small granular crystals. Sodium sulfate is easy to absorb water when exposed to the air, forming sodium sulfate decahydrate, also known as Glauber's salt, which is slightly alkaline.
Sodium sulfate is mainly used in the manufacture of water glass, glass, enamel, pulp, refrigerant mixture, detergent, desiccant, dye diluent, analytical chemical reagent, pharmaceuticals, feed, etc. At 241℃, sodium sulfate will transform into hexagonal crystals. Sodium sulfate is the most commonly used post-treatment desiccant in organic synthesis laboratories. Upstream raw materials include sulfuric acid, caustic soda, etc.

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.
7. Sodium sulfate is a by-product of the production of hydrochloric acid from table salt and sulfuric acid.
9. Industrially used as raw materials for preparing NaOH and H2SO4, and also used in papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc.
10. Sodium sulfate is the most commonly used post-treatment desiccant in organic synthesis laboratories.
11. Mainly used as a filler for synthetic detergents.
12. Used as a laxative in the pharmaceutical industry. It is also used in non-ferrous metallurgy and leather.
13. The hydration product calcium sulfoaluminate is produced faster, thereby accelerating the hydration and hardening speed of cement.
14. Used as an analytical reagent, such as a dehydrating agent, a digestion catalyst for nitrogen determination, and an interference inhibitor in atomic absorption spectroscopy.
15. It can be used as a buffer in sulfate zinc plating to stabilize the pH value of the plating solution.
