Aluminium Fluoride Formula

Aluminium fluoride is a colourless chemical compound with a molecular formula AlF3. It is mainly used in the production of aluminium. It occurs naturally as oskarssonite and rosenbergite. It can be manufactured synthetically too. The majority of aluminium fluoride is produced by treating hydrogen fluoride with alumina or aluminium oxide at 700 °C. In this short piece of article, learn more about aluminium fluoride formula, its chemical structure, properties and uses.
