HYDROFLUOROSILICIC ACID (25% OR LESS) can react with strong acids (such as sulfuric acid) to release fumes of toxic hydrogen fluoride. Attacks glass and materials containing silica. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides).

2017年7月12日 · The three main fluoride compounds generally used to fluoridate water are: sodium fluoride, hydrofluorosilicic acid (hexafluorosilicic acid) and sodium silicofluoride. All these fully mix...

Fluoride is now used in the public drinking water supplied to about 3 out of 4 Americans. The decision to add fluoride to drinking water is made at the state or local level. The types of fluoride added to different water systems include fluorosilicic …

Appearance and Odor: Fuming colorless liquid with pungent odor. Emergency Overview: A corrosive chemical. Harmful if swallowed. Harmful if inhaled. Causes severe skin burns and eye damage. Contact with liquid or vapor form of this chemical may cause severe injury. Avoid overexposure. Acute Toxicity, Oral – Category 4.

Silicofluoric Acid is a fuming, colorless to pale, straw-colored liquid with a sharp, irritating odor. It is used in water fluoridation, metal sterilization, electroplating, animal hide tanning, and glass etching. Silicofluoric Acid is on the Right to Know Hazardous Substance List because it is cited by DOT and IARC.

Hydrofluorosilicic acid: S7 (Dangerous Poison) See the Ixom Safety Data Sheet Hydrofluorosilicic acid. This material is hazardous according to criteria of NOHSC; HAZARDOUS SUBSTANCE. Subclasses: 6.1 Category D: Substances which are acutely toxic. 8.1 Category A: Substances that are corrosive to metals.

2024年7月1日 · Let’s take a closer look at the nature of hydrofluorosilicic acid, its applications, the specific storage concerns and solutions, and safety considerations when working with this complicated chemical.

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.

Fluorosilicic acid, also known as hydrofluorosilicic acid, is a synthetic fluoride compound used in municipal water fluoridation. It is a byproduct of the phosphate fertilizer industry, generated by the wet scrubbing of industrial smokestack emissions to capture hydrogen fluoride gas.

Hydrofluorosilicic acid is used to fluoridate drinking water, to reduce the occurrence of dental caries. In each State and Territory, except for South Australia, the fluoridation of drinking water is regulated by an Act of Parliament; New South Wales and …
