Uses & Benefits
Hydrogen fluoride 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 the hydrogen fluoride 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. Hydrogen fluoride 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.
