Hydrofluoric Acid (HF)
Hydrofluoric acid is an inorganic compound with the chemical formula HF. It is a colorless corrosive liquid with a pungent and pungent odor. Hydrofluoric acid is a strong acid that can react chemically with many substances and has strong corrosiveness and toxicity. In industry, hydrofluoric acid is often used in fields such as metal cleaning, glass etching, and organic synthesis. Due to its danger, strict adherence to safety operating procedures is required when using hydrofluoric acid.

PHYSICAL PROPERTIES
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Solutions of HF are colourless, acidic and highly corrosive.
APPLICATION
The principal use of hydrofluoric acid is in organofluorine chemistry. Many organofluorine compounds are prepared using HF as the fluorine source, including Teflon, fluoropolymers, fluorocarbons, and refrigerants such as freon. Many pharmaceuticals contain fluorine.
Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid. Foremost are Na3AlF6, cryolite, and AlF3, aluminium trifluoride. A molten mixture of these solids serves as a high-temperature solvent for the production of metallic aluminium. Other inorganic fluorides prepared from hydrofluoric acid include sodium fluoride and uranium hexafluoride.
Hydrofluoric Acid is used in the semiconductor industry as a major component of Wright etch and buffered oxide etch, which are used to clean silicon wafers. In a similar manner it is also used to etch glass by treatment with silicon dioxide to form gaseous or water-soluble silicon fluorides. It can also be used to polish and frost glass.
