CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Sodium fluorosilicate is a fine, white, odorless, powdered solid. Toxic by ingestion, inhalation and skin absorption. Used as a rodenticide.
Color/Form WHITE GRANULAR POWDER
Odor Odorless
Taste Tasteless.
Melting Point Melts at red heat with decomposition.
Solubility SOL IN 150 PARTS COLD, 40 PARTS BOILING WATER; INSOL IN ALCOHOL
Density 2.68 at 68 °F (USCG, 1999) - Denser than water; will sink
Decomposition When heated to decomposition it emits toxic fumes of /hydrogen fluoride/ and Na2O.
pH SOLN IN COLD WATER IS NEUTRAL
Refractive Index INDEX OF REFRACTION: 1.312, 1.309
Other 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/
Chemical Classes Metals -> Metals, Inorganic Compounds
