Sodium sulfate

Sodium sulfate, also known as sodium sulfate anhydrous (Yuanmingfen), is an inorganic compound. Generally, it exists in two forms. One is the anhydrous form, with the chemical formula Na₂SO₄. It is a white crystalline powder, odorless and having a bitter taste. The other form is that one sodium sulfate molecule is combined with ten water molecules, which is called sodium sulfate decahydrate, also known as mirabilite, and its chemical formula is Na₂SO₄·10H₂O. It can remain stable in dry air and has strong hygroscopicity. It is easily soluble in water, and the solution is generally colorless. The aqueous solution is neutral or slightly alkaline. At different temperatures, the solubility of sodium sulfate in water varies. Generally speaking, as the temperature rises, the solubility increases. It is insoluble in ethanol, strong acids, aluminum, and magnesium, but soluble in glycerol. The melting point of anhydrous sodium sulfate is 884°C, and the boiling point is 1404°C.

Application Scope

1.Basic Chemical Raw Material: It is an important raw material used for the manufacture of other chemical products such as sodium sulfide, sodium silicate, water glass, etc.

Sodium sulfate
2.In the glass industry, it can be used as a fluxing agent, which can lower the melting point of glass and improve the transparency and glossiness of the glass.

Sodium sulfate
3.In the paper-making industry, it is used for manufacturing sulfate pulp, which can enhance the strength and whiteness of the paper.

Sodium sulfate
4.In the textile industry, it is used to prepare the spinning coagulant for vinylon.

Sodium sulfate
5.In the printing and dyeing industry, it is used as a dye accelerant, which can increase the dye uptake rate of dyes.

Sodium sulfate
6.In the leather industry, it is used in the processes such as the depilation and tanning of leather.
7. In the detergent industry, it serves as a filler and an auxiliary agent, which can enhance the detergency of the detergent.
8.In the pharmaceutical industry, mirabilite (sodium sulfate decahydrate) has the effects of purgation and clearing heat, and can be used to treat diseases such as constipation and edema. Sodium sulfate can also serve as a pharmaceutical intermediate for the synthesis of other drugs.

Sodium sulfate
9.In the ceramic industry: It is used to adjust the viscosity of ceramic body materials and increase their adhesiveness. When used in the surface coatings of ceramic products, it can improve the quality and glossiness of the coatings.
10.In the building materials industry: Adding sodium sulfate anhydrous (Yuanmingfen) to cement can accelerate the hydration and hardening speed of the cement, and improve the early strength of the concrete.
