Hydrofluoric Acid

Hydrofluoric acid is a highly reactive and corrosive inorganic acid widely used in industrial manufacturing, chemical processing, and specialty applications. Known for its ability to dissolve oxides and silicates, HF is essential in metal treatment, glass etching, semiconductor manufacturing, and fluorine compound synthesis. Its unique reactivity with silica makes it a critical chemical for industries requiring precision surface treatment and high-purity processing.

In addition to surface treatment, hydrofluoric acid functions as a catalyst, etchant, and intermediate in the production of refrigerants, fluoropolymers, pharmaceuticals, and agrochemicals. It also plays a role in petroleum refining (alkylation), rare earth element processing, and high-performance material development. With its unmatched chemical properties and wide-ranging industrial importance, hydrofluoric acid remains a vital raw material across electronics, automotive, aerospace, construction, and specialty chemical manufacturing.
