    Sodium fluorosilicate appears as white crystal, crystalline powder or colorless

     

    hexagonal crystals. It is odorless and tasteless. Its relative density is 2.68;

     

    it has moisture absorption capability. It can be dissolved in a solvent such as ethyl

     

    ether but insoluble in alcohol. The solubility in acid is greater than that in water.

     

    It can be decomposed in alkaline solution, generating sodium fluoride and silica.

     

    After searing (300 ℃), it is decomposed into sodium fluoride and silicon

     

    tetrafluoride. It is poisonous!
     

      In 25 degrees, the sodium fluorosilicate has its water solubility being 0.78%.

     

    Upon production, addition of an excess amount of sodium sulfate or sodium

     

    chloride can increase the concentration of sodium ions in the system, thereby

     

    increasing the solubility product of fluorine silicate and sodium ions, so that sodium

     

    fluoride can be subject to more complete precipitation. 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.

    ►Toxicity

          This product is toxic with stimulation effect on the respiratory organ. People of

     

    mistakenly oral poisoning will get severe symptoms of damage to the

     

    gastrointestinal tract with the lethal dose being 0.4~4g. During the working of the

     

    operator, they should wear the necessary protective equipment to prevent

     

    poisoning. Production equipment should be sealed and the workshop should be

     

    well ventilated.

    Application 

     

    Sodium fluorosilicate can be used as:

    1. The insecticide in agriculture.

    2. Opal glass 

    ►Storage characteristics

     

    Treasury: ventilation, low-temperature and drying; store it separately from food and

     

    acid.
