    HAZARD CLASS

     

                             6.1

     

     

    1. Appearance :White, crystalline powder.

     

     

    2. Production method:Sodium fluorosilicate is made by neutralizing fluorosilicic

     

    acid with sodium chloride or sodium sulfate.

     

     

    3. Features: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!
