- Product Identification
CAS No. : 16893-85-9
H.S. Code : 2826.901000
Formula : Na2SiF6
Molecular Weight : 188.06
Toxicity : highly toxic to all plant and animal life
Synonyms : Sodium Silicofluoride; Sodium Hexafluorosilicate; Sodium Fluosilicate; Earwig Bait; Disodium Hexafluorosilicate
Raw Materials : fluorosilicic acid with sodium carbonate
- Physical And Chemical Properties
Physical State : (Apperance) It is colorless hexagonal, odorless and tasteless crystal with relative density 2.679. It is hygroscopic. It is soluble in ether, insoluble in alcohol. The solubility in acid is greater than in water. It decomposes in alkaline solution and produces sodium fluoride and silicon dioxide. It is decomposed to sodium fluoride and silicon tetrafluoride by heating to 300'C. It is noxious!
Specific Gravity : 2.679
Solubility in Water : 0.76 g/100 ml at 25oC , 2.45 g/100 ml at 100 oC
- Applications
It is used as antiseptic in timber industry, hygroscopic agent of acid-resisting concrete, solidifying agent in natural latex products, additive in plating with zinc, nickel, iron and filler in plastic and fluorinating agent in pharmaceuticals and drinking water. It is used to produce insecticide in pesticide industry and sodium fluoride in man-made cryolite.

Flammability characteristics:Non-combustible; toxic fluoride and sodium oxide, silicon oxide fumes are emitted from the fire; react with acid to generate toxic hydrogen fluoride
Odor:Odorless
Taste:Tasteless.
PH:SOLN IN COLD WATER IS NEUTRAL
Experimental Properties:Solutions of fluosilicates are sensitive to hydrolysis in alkaline medium. In the presence of acid, fluosilicate solutions release silicon tetrafluoride. The thermal decomposition of fluosilicates takes place with release of gaseous silicon tetrfluoride and formation of the solid fluoride. /Fluosilicates/
Air and Water Reactions:Water soluble.
Reactive Group:Salts, Basic
Reactivity Profile:SODIUM FLUOROSILICATE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. Solutions of sodium fluorosilicate may contain some hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass. Unlike other halide ions, fluoride is quite reactive, acting as a weak base and participating in some unique reactions. In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass.
