Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. Sodium hexafluorosilicate has also been used for caries control as part of a silicophosphate cement, an acidic gel in combination with monocalcium phosphate monohydrate, and a two-solution fluoride mouth rinse. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. 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] hydrofluosilicic acid synonyms, hydrofluosilicic acid pronunciation, ... Noun 1. hydrofluosilicic acid - an unstable poisonous corrosive acid known primarily in the form of its salts fluosilicic acid acid - any of various... Hydrofluosilicic acid - definition of hydrofluosilicic acid by The Free Dictionary. Fluorosilicic acid is also used to make aluminum fluoride for the aluminum industry. Used in water fluoridation, in hardening cement and ceramics, as a wood preservative. Fluosilicic acid - Identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information Note : See Working with the Information on this Page section below for important notes about this data. Fluosilicic acid (FSA) is obtained in large quantities as a by-product from wet phosphoric acid and phosphate fertiliser plants.

Attacks many metals. Fluosilicic acid. Unlikely to suffer scaling. If a market cannot be found for the fluosilicic acid, it can then be neutralized with phosphate rock to produce a weak phosphoric acid. When heated to decomposition (1050 C) it emits highly toxic and corrosive fumes of Hydrogen Fluoride, Silicon Tetrafluoride and Hydrogen gas. Fluorosilicic acid appears as a colorless fuming liquid with a penetrating pungent odor. “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. The solution of fluosilicic acid and ammonium fluosilicate, or ammonium fluosilicate alone if ammonium fluoride is used for scrubbing, is reacted with ammonia thereby converting the fluorine-containing salts to ammonium fluoride and regenerating the colloidal silica for recycle to the phosphoric acid concentrators. A better environmental alternative is to use scrubbers to remove fluorides as fluosilicic acid prior to condensing the vapors in barometric condensers. These technologies are well proven over 50 years at a wide range of capacities and have been sold world-wide. a. mixing the crude gypsum with an aqueous fluosilicic acid (hydrofluosilicic acid, silicofluoric acid (H 2 SiF 6)) solution at about 160°-195° F. to obtain a liquid phase and a solid phase; b. separating the liquid phase from the solid phase (e.g., by filtration, centrifugation, or decantation) while maintaining the temperature of the liquid phase within a range of about 160°-195° F.; Consumer Uses .
