The chemical formula of sodium sulfate is Na2SO4. Sodium sulfate is soluble in water. Most of its solutions are neutral, soluble in glycerol but not soluble in ethanol. Inorganic compounds, anhydrous substances with high purity and fine particles are called Yuanming powder.

White, odorless, bitter crystals or powder, hygroscopic, appearance is colorless, transparent, large crystals or granular small crystals. Sodium sulfate easily absorbs water when exposed to air and forms sodium sulfate decahydrate.

Mainly used for manufacturing water glass, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, feed, etc. Sodium sulfate will transform into hexagonal crystals at 241°C.

Extended information:

Mainly used as filler for synthetic detergents. Cooking agent used in the paper industry in the manufacture of kraft pulp. Used in the glass industry to replace soda ash. In the chemical industry, it is used as raw material for the manufacture of sodium sulfide, sodium silicate and other chemical products.

The hydration product calcium sulfoaluminate is generated faster, thus accelerating the hydration and hardening speed of cement. The dosage of sodium sulfate is generally 0.5% to 2% of the cement mass, which can increase the early strength of concrete by 50% to 100%. The 28-day strength sometimes increases, sometimes decreases, and the increase is about 10%;

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.
