Hydrofluoric Acid (HF)

Description

Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water, distinguished by its ability to dissolve materials such as glass and metals like sodium and potassium. This characteristic is due to the fluoride ion’s small size and high electronegativity.

HF is produced by reacting calcium fluoride (fluorite) with sulfuric acid to produce hydrogen fluoride gas, which is then dissolved in water to form hydrofluoric acid in varying concentrations. Unlike other acids, HF can react with oxides and metals to form fluoride salts and can etch glass and silica, producing silicon tetrafluoride gas. It typically appears as a colourless solution, but higher concentrations may present as a fuming liquid.

Our Hydrofluoric Acid is synthesised to meet high purity standards, ensuring it fulfils industrial requirements. It’s effective and precise, available in different concentrations for varied industrial needs. Rigorous quality controls guarantee consistent and reliable quality. For safety, it’s packaged in HF-resistant containers and offered in sizes ranging from small for detailed applications to bulk for larger-scale uses.
