ZINC SILICOFLUORIDE Usage And Synthesis
DescriptionIt has widespread applications including fast hardener for concrete, wood preservative, plaster enhancer, postscrubbing agent, mothproofing agent, catalyst for the production of polyester fibre, and ingredient in electrolytic bath for preparing zinc. Moreover, it may act as an active agent in mould-resistant emulsion paints.1 This chemical may also be used as an additive for hardening and polishing the concrete surface, such as a floor or wall.2 In addition, a pasty mixture prepared by mixing zinc fluosilicate with other chemicals shows a desirable function for cleaning stone, bricks, concrete, and other constructional material.3 Besides, the use of this compound in the froth-flotation process aids in effecting selection of valuable mineral.4

Chemical PropertiesWhite crystals.Decomposes on heating; soluble in water.
General DescriptionA solid material, or the solid mixed with water. Insoluble in water and denser than water. Contact with the material may cause irritation to skin, eyes, and mucous membranes. ZINC SILICOFLUORIDE may be toxic by ingestion.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileZINC SILICOFLUORIDE 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.
Health HazardInhalation of dust irritates nose and throat; excessive inhalation may cause severe pulmonary inflammation. Ingestion causes nausea, cramps, vomiting, shock, convulsions, cyanosis, and other symptoms of fluoride poisoning. Contact with eyes or skin causes irritation; skin ulcers may develop.
Fire HazardSpecial Hazards of Combustion Products: Toxic and irritating hydrogen fluoride and silicon tetrafluoride are formed in fires.
Safety ProfilePoison by ingestion and subcutaneous routes. When heated to decomposition it emits toxic fumes of F- and ZnO. See also ZINC COMPOUNDS.
