Barium sulphate for glass

Short Description:

Colorless orthorhombic crystal or white amorphous powder. The relative density is 4.30. The melting point is 1580°C. Almost insoluble in water, ethanol and acid. Dissolved in hot concentrated sulfuric acid, it is easy to agglomerate when dry. Carbon can be reduced to barium sulfide at 600°C.

Use of barium sulfate for glass:

Mainly used in glass products, as a clarifying agent of glass, can play the role of defoaming and increasing gloss.

Barium sulphate for glass is used in glass manufacturing industry to clarify glass products. The ultra-fine barium sulphate product is produced by using high-grade barium sulphate ore with the current international leading technology. The product is dense particles with a narrow particle size distribution and high chemical stability. Barium sulphate content is more than 98%, high whiteness, no black spots, no impurities, good dispersion, good wettability, excellent acid resistance, high temperature resistance, and corrosion resistance. Can significantly improve the hardness and wear resistance of products.

  Product Features:  

   1. The particle size distribution is narrow, with a small specific surface area and the amount of base material, high gloss and fluidity can be obtained;

   2. Highly inert chemical substances, acid and alkali resistance, good sun resistance and weather resistance;

   3. high purity, few impurities, no trace of ore and salt impurities (no corrosion or sulfide components);

4. It can improve the strength, wear resistance and geometric stability of products;

   5. Good compatibility with the matrix and close combination

   6. stable pigments

7. easy to disperse.
