Sodium fluorosilicate Chemical Properties,Uses,Production
Chemical Properties
white powder
Uses
In enamels for china and porcelain; manufacture of opal glass; as insecticide, rodenticide; mothproofing of woolens. Fluoridating agent for drinking water. Intermediate in production of synthetic cryolite.
General Description
Fine, white, odorless, powdered solid. Toxic by ingestion, inhalation and skin absorption. Used as a rodenticide.
Air & Water Reactions
Water soluble.
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.
Hazard
Toxic by ingestion and inhalation, strong irritant to tissue.
Health Hazard
Inhalation of dust may irritate nose and throat. Ingestion causes symptoms similar to fluoride poisoning; compound is highly toxic; initial symptoms include nausea, cramps, vomiting, diarrhea, and dehydration; in severe cases, convulsions, shock, and cyanosis are followed by death in 2-4 hr. Contact with eyes causes irritation. Contact with skin causes rash, redness, and burning, sometimes followed by ulcer formation.
Fire Hazard
Behavior in Fire: Decomposes at red heat
Industrial uses
Sodium fluorosilicate (Na2SiF6) is a white, isomorphous powder. Solubility in water is similar to that of NaF. In
acid pH, solubility improves.
Commercially, Na2SiF6 is produced by treatment of fluorosilic acid with sodium chloride,
as shown in the following reaction:
H2SiF6 + 2NaCl = Na2SiF6 + 2HCl
Safety Profile
Poison by ingestion and subcutaneous routes. A skin and severe eye irritant. An insecticide. When heated to decomposition it emits very toxic fumes of Fand Na2O.
Potential Exposure
Sodium hexafluorosilicate is as a rodenticide; as an intermediate in production of synthetic cyrolite; as an insecticide in delousing and in mothproofing of woolens.
Shipping
UN2674/Sodium fluorosilicate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification Methods
Crystallise it from hot water (40mL/g) by cooling.
Incompatibilities
Reacts with acids to produce hydrogen fluoride, a highly corrosive and poisonous gas.
