Sodium Silicates   HOME > Product > Sodium Silicates

1. Molecular formula: Na2O-nSiO2-xH2O

2. Sodium silicate among water ?solubility silicates is the inorganic compound to be used the most wide

3. Because of water solubility, it is called “water glass” also.

4. According to the mole ratio of SiO2/Na2O and concentration,It has various properties and application.

5. The calculation of molar ratio
[Molar ratio of sodium silicate = Weight ratio of SiO2/Na2OⅩ1.032]

1. A hardening of soil, accelerating agency of cement.
2. Synthetic detergent, Soap
3. loose fiber dyeing, Paper for newspaper
4. Covering material for welding rod
5. Sewage treatment
6. Casting hardener
7. Raw material for White carbon, Zeolite, Silica
8. Raw material for Ceramics and sanitary pottery
9. Refractory binder
