Tell you something about Ammonium bifluoride

Ammonium bifluoride, we also call it Ammonium difluoride, Ammonium acid fluoride or Ammonium hydrogen difluoride, its CAS NO is 1341-49-7. Ammonium bifluoride (NH 4•HF2) is manufactured and sold in solid form or in aqueous solutions. The solid is a white crystal. The so lutions are clear, colorless liquids that have a slightly sharp, pungent odor. Common industrial solution strength concentrations are between 28 and 30%.

The ammonium bifluoride market in North  America is estimated to be between 7 and 9 million pounds. Solvay Fluorides, LLC’s Mexican affiliate is the only North American producer of solid ABF. Solvay  Fluorides makes an ABF soluti on for sale. Solvay’s North American production facilities for this chemical are located in northern Mexico and in the central United States.

Solvay manufactures solid ammonium bi fluoride by mixing a mmonia and anhydrous hydrogen fluoride (liquid) together and then drying to form flakes. Ammonium bifluoride solution is made by dissolving solid ammonium bifluoride in water.

Ammonium bifluoride is used for cleaning and etching of metals before they are further processed. It is used as an oil well acid ifier and in the etching of glass or cleaning of brick and ceramics. It may also be used for pH adjustment in industrial textile processing or laundries. ABF is available as a  solid or liquid solution (in water).Consumer products containing ammonium bifluoride are primarily products for the etching of glass (hobby) or for ce ramic and brick cleaners.

Solvay Fluorides LLC does not sell ammonium bifluoride directly to consumers. Ammonium bifluoride is used in industrial applications and in other processes where workplace exposures can occur.

Ammonium bifluoride is a corrosive chemical and contact can severely irritate and burn the skin and eyes causing possible permanent eye damage. Breathing ammo nium bifluoride can severely irritate and burn the nose, throat, and lungs, causing nosebleeds, cough, wheezing and shortness of breath. On contact with water or moist skin, ABF can release hydrofluoric acid, a very dangerous acid.

Inhalation or ingestion of large amounts  of ammonium bifluoride can cause nausea, vomiting and loss of appetite. Very high or long term exposures can cause fluoride poisoning with stomach pain,  weakness, convulsions and death. Long term or repeated exposures can cause deposits of fluorides in bones and teeth, a condition called Fluorosis. This may cause pain, disability and discoloration of teeth.

These are just basic thing about Ammonium bifluoride, last time, I will give more details. Thank you!!
