Description 

 

      Sodium fluorosilicate is the byproduct in the production of calcium phosphate or

 

the production of fluoride salt in aluminum factory.

     

      It generally appears as a white crystalline powder with low solubility in water

 

(being 1% or less at room temperature), and the water solubility increases slightly

 

with increasing temperature.

     

      The aqueous solution of sodium fluorosilicate is acidic (pH3). This is due to that

 

its hydrolysis product contains hydrofluoric acid.

   

   

         When pH is lower than 3.5-3.55, the hydrolysis reaction is stabilized. When

 

the pH is equal to 4, the hydrolysis reaction rate is significant. When the pH value is

 

equal to 8-8.5, the sodium fluorosilicate can be completely hydrolyzed to exhibit as

 

silica gel and precipitated out.

     

            Therefore, when sodium fluorosilicate is added to the water glass, in addition

 

to hardening effect of precipitation of silicon dioxide gel caused by the neutralization

 

of the sodium hydroxide in the solution of water glass, the sodium fluorosilicate

 

itself is also a source of silica gel.
