 ►Description 
 
Origin :Sodium fluorosilicate is made by neutralizing fluorosilicic acid with
 
sodium chloride or sodium sulfate. 
Appearance : Fine, white, odorless, powdered solid
production method: Sodium fluorosilicate is made by neutralizing fluorosilicic acid

with sodium chloride or sodium sulfate. 
 Usage : Additives for water fluoridation, ore refining, or other fluoride chemical (like

 
sodium fluoride, magnesium silicofluoride, cryolite, aluminum fluoride) production.in
 
the field of laundry souring, manufacturing enamels, manufacturing coated papers,
 
wood preservative , foam production, opal glass,ore flotation and water fluoridation.
 

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!
