1. Chemical name: sodium sulfate
2. Molecular formula: Sodium sulfate anhydrous: Na2SO4 Sodium sulfate decahydrate: Na2SO4·10H2O
3. Molecular weight: anhydrous: 142.04; decahydrate: 322.20
4. CAS: Anhydrous: 7757-82-6; Decahydrate: 7727-73-3
5. Performance: White monoclinic crystal or powder, odorless, with a bitter and salty taste; also known as Glauber's salt and Yuanming powder. It is soluble in water and glycerin, but insoluble in ethanol. When exposed to the air, it easily absorbs moisture and becomes hydrated sodium sulfate. .
6. Usage: Mainly used for manufacturing water glass, enamel, pulp, desiccant, analytical chemical reagents, etc.
7. Packaging: lined with polyethylene plastic bag, outer plastic woven bag, 25Kg per bag.
8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse, handled with care, to prevent moisture and heat. During transportation, it should be protected from rain and moisture, and should be isolated and stacked away from toxic substances.
Sodium sulfate, inorganic compound, sodium sulphate decahydrate also known as glauber's salt, high purity, fine particles of anhydrous substances called yuanming powder. Yuanming powder, white, odorless, bitter crystal or powder, has hygroscopic properties. The shape is colorless, transparent, large crystals or small particles. It is mainly used for making water glass, glass, porcelain glaze, pulp, refrigeration mixer, detergent, desiccant, dye thinner, analytical chemical reagent, pharmaceuticals, etc.

The main purpose
1. In the chemical industry, it is used to manufacture sodium sulfide sodium silicate water glass and other chemical products.
2. It is used in the paper industry as a cooking agent for the manufacture of kraft pulp.
3. The glass industry is used to replace soda ash as a co-solvent.
4. The textile industry is used to prepare vinylon spinning coagulant.
5, for non-ferrous metal metallurgy, leather and so on.
6. It is used to make sodium sulfide, pulp, glass, water glass, enamel, and also used as laxative and antidote for barium salt poisoning. Chemically used in the manufacture of sodium sulfide, sodium silicate, etc. Laboratory use to wash away barium salts. In industry, it is used as the raw material for the preparation of NaOH and HSO, and is also used in papermaking, glass, printing and dyeing, synthetic fiber, leather making, etc. Sodium sulfate is one of the most commonly used post-processing desiccants in organic synthesis laboratories.
7. Mainly used as a filler for synthetic detergents. Cooking agent used in the paper industry to make kraft pulp. Glass industry 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. Textile industry is used to prepare vinylon spinning coagulation bath. The pharmaceutical industry is used as a laxative. Also used in non-ferrous metallurgy, leather and so on.
8. The hydration product calcium sulfoaluminate is generated faster, thereby accelerating the hydration and hardening speed of cement. The dosage of sodium sulfate is generally 0.5%~2% of the cement quality, which can improve the early strength of concrete by 50%~100%. The 28-day strength sometimes increases, sometimes decreases, and the increase rate is about 10%. and its dosage 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 analytical reagents, such as dehydrating agents, digestion catalysts in nitrogen determination, and interference inhibitors in atomic absorption spectrometry. Also used in the pharmaceutical industry.
10. It is used in chemical industry, papermaking and glass, dyestuff, 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 bath.
