Uses and Industrial Applications of Hydrofluoric Acid
What is Hydrofluoric Acid? Hydrofluoric acid is an aqueous form of hydrogen fluoride ''s considered to be a corrosive and colorless acid that can be dangerous when it comes into contact with skin, eyes, or lungs. Despite these dangers, the natural reactivity of this acid makes it highly effective when used for industrial applications.
Hydrogen Fluoride
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.

Safer Options to Hydrofluoric Acid (HF) in Industrial Cleaning
Hydrofluoric acid is a highly reactive acid with many hazards. Not only is HF extremely corrosive, it is also a contact poison making it extremely dangerous to handle, use and apply. Unlike other acids that cause immediate superficial burns, HF rapidly penetrates deep into the skin damaging tissues, bones and the nervous system.
Hydrofluoric Acid
Hydrofluoric acid (HF) differs from other acids because it readily penetrates the skin and dissociates into fluoride ions, causing destruction of deep tissue layers, including bone. Pain associated with skin exposure to HF may not occur for 1-24 hours. Unless you can rapidly neutralize the HF and bind the fluoride ions, tissue destruction may ...
