Aluminium Fluoride

Aluminium Fluoride comprises a white bulk material of crystal structure.

95 per cent of global aluminium fluoride production are used to manufacture aluminium and glass, optical products and leather products.

We manufacture aluminium fluoride by using the waste product extracted during phosphoric acid production process - silica hexafluorosilicic acid - and neutralizing it with aluminium hydroxide.

Lifosa's annual production of aluminium fluoride amounts to

21,000 tons.
