    ►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.

         

             Reduction of the acidicity of the solution facilitates the hydrolysis of sodium

     

    fluorosilicate.

         

             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.

    Chemical Properties

        It appears as colorless hexagonal crystals. It is odorless and tasteless. It has

     

    hygroscopicity. It can be dissolved in a solvent such as ethyl ether but insoluble in

     

    alcohol with its solubility in acid is being greater than in the water.
