Description
Pure Sodium Silicate Fluoride For Agriculture Insecticide CAS 16893 85 9

 White powder sodium Fluorosilicate using in agriculture as

insecticide CAS NO 16893-85-9

►Description    

      Sodium fluorosilicate is a Fine, white, odorless, powdered solid .And it is

 

madeby neutralizing fluorosilicic acid with sodium chloride or sodium

 

sulfate.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!
