1.8.2 Hydrofluosilicic Acid: Hydrofluosilicic acid (HFA), or hydrofluorosilicic acid, or fluosilicic acid is an aqueous solution of H 2 SiF 6. Fluosilicic acid (FSA) is obtained in large quantities as a by-product from wet phosphoric acid and phosphate fertiliser plants. It is used to convert aluminum ore into aluminum metal, to refine lead, as a reagent in organic synthesis, etc. Sources/Uses Used as a chemical intermediate, a disinfectant, a water fluoridating agent, a wood preservative, a masonry and ceramic hardener, and a glass additive; it is also used to treat hides and skins, to electroplate chromium, and to electrolytically refine lead; [HSDB] Used in technical paints, oil well acidizing, and to remove mold, rust, and stains from textiles; [NTP] Search results for fluorosilicic acid at Sigma-Aldrich. Where a substantial concentration of fluosilicic acid (more than 22% H 2 SiF 6) and a high yield is required, two absorption towers may be used together. Both chemicals are also used as a chemical intermediate (raw material) for aluminum trifluoride, cryolite (Na3AlF6), silicon tetrafluoride, and other fluorosilicates and have found applications in commercial laundry. Domestic production data for About 41,200, 4,700, and 13,200 tons of byproduct fluorosilicic acid were sold for water fluoridation, AlF3 production for the aluminum industry, and for other uses, such as sodium silicofluoride production, respectively. In case of fire in the surroundings: use appropriate extinguishing media. hydrofluosilicic acid, sodium fluoride and sodium silicofluoride, presently used for fluoridation of water. Consumer Uses . “In regard to the use of fluosilicic acid as the source of fluoride for fluoridation, this agency regards such use as an ideal solution to a long standing problem. for the forecast year up to 2029. A chemical profile of the acid byproduct used is presented in table 2.

The slag samples were leached using fluosilicic acid (H2SiF6), a byproduct of the fertilizer industry. Fluosilicic acid concentrates in pools and spas over time while water evaporates. disinfectants, pest control products) and … Attacks many metals. Fluosilicic synonyms, Fluosilicic pronunciation, Fluosilicic translation, English dictionary definition of Fluosilicic. When heated to decomposition (1050 C) it emits highly toxic and corrosive fumes of Hydrogen Fluoride, Silicon Tetrafluoride and Hydrogen gas. A better environmental alternative is to use scrubbers to remove fluorides as fluosilicic acid prior to condensing the vapors in barometric condensers. The fluosilicic acid are carefully produced without hampering their molecular compositions. If a market cannot be found for the fluosilicic acid, it can then be neutralized with phosphate rock to produce a weak phosphoric acid. Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. The majority of the fluosilicic acid is converted to. Buss ChemTech is the market leader for fluorine chemical process technologies. Fluosilicic acid. Decomposes on heating. These fluosilicic acid solutions are in their purest form and have a water solubility of up to 100%. The chemical reaction is employed, not for our health, but to slow down the corrosive action of fluosilicic acid on the water district's plumbing metal valves. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). Such a configuration is recommended when the phosphoric acid has a concentration of up to 42-46% P 2 O 5. Purity Requirements: Analyses of available grades of fluosilicic acid show the presence of arsenic and lead but at levels far below that which would necessitate RMIC values based on a maximum dosage of 1.2 mg of fluoride ion/liter.
