Sodium Sulfate Anhydrous 99% Na2SO4
Sodium sulfate (NA2SO4) is sulfate and sodium ions generated salt and sodium sulfate soluble in water, its solution for neutral, mostly for alkaline soluble water, soluble in glycerin and not soluble in ethanol.
Inorganic compound, high purity, fine particles of anhydrous substance called yuanming powder.
Yuanming powder, white, odorless, bitter crystals or powder, hygroscopic.
Shape is colorless, transparent, large crystals or granular small crystals.
Sodium sulfate is easy to absorb water when exposed to air, resulting in sodium dechydrate, also known as glauber's salt, which is slightly alkaline.
Application: Mainly used in the manufacture of sodium silicate, glass, porcelain glaze, paper pulp, refrigerant mixture, detergent, desiccant, dye diluent, analytical chemical reagents, pharmaceuticals, feed and so on.
At 241ºC, sodium sulfate will be converted into hexagonal crystals.
Sodium sulfate is one of the most commonly used post-treatment desiccant in organic synthesis laboratories.
Upstream raw materials include sulfuric acid, caustic soda and so on.
