Overview of Hexafluorosilicic Acid

Hexafluorosilicic Acid (H₂SiF₆) is a highly corrosive, clear, and strongly acidic industrial chemical widely used in fluoridation, metal treatment, fertiliser production, and advanced chemical synthesis. Known for its strong fluoride ion release, it plays a key role in water treatment, glass processing, and manufacturing fluorine-based intermediates.

This chemical is valued for its reactivity, solubility, and efficiency in industrial processes. ChemicalBull supplies high-purity Hexafluorosilicic Acid suitable for large-scale industrial use, R&D labs, and regulated manufacturing applications.
