Ammonium hexafluoroaluminate is an inorganic compound with the chemical formula of (NH4)3[AlF6]. It is a white solid. Upon heating, it converts to aluminium trifluoride, a reaction that releases hydrogen fluoride.[1] It has also been used as a precursor to zeolites.[2]

Preparation

Ammonium hexafluoroaluminate can be obtained by the reaction of ammonium fluoride and aluminium hydroxide.[3]
