Product Description
Sodium Silicofluoride powder Na2SiF6 CAS NO 16893-85-9 can use as additives for water fluoridation and opal glass
►Description
Sodium Fluorosilicate is a fine, white, odorless, powdered solid. Toxic by ingestion,
inhalation and skin absorption.
1. Appearance :
White, hexagonal crystals.
2. production method:
Sodium fluorosilicate is made by neutralizing fluorosilicic acid with sodium chloride
or sodium sulfate.
3. 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.
4. Features:
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!
