Top sodium cacodylate Supply for medicine and drinking water industry

♦ Specification 

♦ 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.
