Sodium Fluorosilicate is a fine, white, odorless, powdered solid. Toxic by
ingestion, inhalation and skin absorption.
|white granular powder|
|Solubility in water|| 0.64 g/100 mL (20 °C)
1.27 g/100 mL (50 °C)
2.45 g/100 mL (100 °C)
|insoluble in alcohol|
Refractive index (nD)
Lethal dose or concentration (LD, LC):
|LDLo (lowest published)||
70 mg/kg (mouse, oral)
|Other cations|| Ammonium hexafluorosilicate
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!
|Loss of Weight on drying at 105°C||≤0.40%|
|Insoluble in Water||≤0.50%|
It appears as colorless hexagonal crystals. It is odorless and tasteless. It has
hygroscopicity. It can be dissolved in a solvent such as ethyl ether but insoluble in
alcohol with its solubility in acid is being greater than in the water.
