Product Description

Product Description

Chemical Formula and Composition
- Anhydrous sodium sulfate has the chemical formula Na2SO4. It consists of sodium (Na+) and sulfate (SO4²-) ions. This simple chemical structure gives it distinct chemical properties.

Physical Properties
- It appears as white crystalline powder or colorless monoclinic crystals. Anhydrous sodium sulfate is odorless and has a relatively high melting point of about 884 °C. It is soluble in water, but its solubility varies with temperature. 

Production Methods
- One common production method is the reaction between sulfuric acid and NaOH. Another way is to extract it from natural minerals such as mirabilite, which is then processed to remove water and impurities to obtain anhydrous sodium sulfate. 

Industrial Applications
- In the paper industry, it is used to adjust the pH value and improve the quality of paper. In the detergent industry, it serves as a filler and bulking agent. It is also widely used in the glass manufacturing industry to improve the melting properties of glass. 

Other Applications
- In laboratories, it is often used as a desiccant to remove water from organic solvents. In the textile industry, it helps in dyeing processes by promoting the uptake of dyes by fabrics.

Application

Glass Manufacturing
In glass production, industrial-grade anhydrous sodium sulfate acts as a flux. It reduces the melting point of raw materials, facilitating the glass-making process and improving the quality of the final product. 
Detergent Industry
It is used as a filler in detergents. Adding it helps to adjust the density and fluidity of detergent powders, making the production process more efficient and cost-effective.
Paper Industry
Industrial-grade anhydrous sodium sulfate plays a role in paper manufacturing. It can improve the strength and whiteness of paper during the production process, enhancing the overall quality of paper products.
Chemical Industry
In the chemical industry, it serves as a raw material for producing other sodium-based chemicals. It participates in various chemical reactions to synthesize different compounds for diverse industrial applications. 
Textile Dyeing
For textile dyeing, it is used to promote the dye-fixation process. It helps dyes adhere better to fabrics, resulting in more vibrant and long-lasting colors.
