Hydrogen fluoride is a colorless, acidic, and highly corrosive fuming liquid or gas with a strong, irritating odor. Other names are Fluorhydric acid and Hydronium fluoride. It is usually shipped in steel cylinders as a compressed gas. it readily dissolves in water to form colorless hydrofluoric acid solutions; dilute solutions are visibly indistinguishable from water.
Hydrogen fluoride, anhydrous appears as a colorless fuming liquid boiling at 67°F. Shipped as a liquid confined under its own vapor pressure. Corrosive to metals and tissue. Very short contact with fumes or small quantities of the liquid can cause severe, painful burns. Vapors are heavier than air. Density 8.2 lb / gal.
It used as a catalyst and raw material in chemical manufacture and common use to etch glass and silicon wafers. When hydrofluoric acid comes into contact with human skin it causes deep burns. It is an industrial raw material used in the manufacture of products including refrigerants, gasoline, and aluminum. Anhydrous hydrogen fluoride (anhydrous means a chemical that contains no water) is the building-block material for the production of fluorine and fluorine-containing products such as fluorochemicals, fluoropolymers, and surfactants. Shanghai Chemex is one of the most reputable manufacturers of this chemical in the world.
Physical and Chemical properties of HF
It is used to make refrigerants, herbicides, pharmaceuticals, gasoline, stainless steel kitchen products, aluminum, plastics, electrical components, and incandescent light bulbs (electric light with a wire filament, used in appliances, incubators, portable lighting).
Sixty percent of this substance used in manufacturing is for processes to make refrigerants used in refrigeration, freezer, and air conditioning systems. In laboratories and industrial settings, hydrofluoric acid can be used for etching glass and enamel, removing rust, and cleaning brass and crystal.
It also is used in manufacturing silicon semiconductor chips.it also is used as an alkylation catalyst in oil refineries to make high-octane gasoline as well as power nuclear reactors.
Cleaners and Rust Removers:
Due to its strong corrosive qualities, a diluted form of hydrofluoric acid is used in some commercial automotive cleaners, rust and stain removers, and water-spot removers
