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!
