Ammonium hexafluoroaluminate Usage And Synthesis

Chemical Properties

White crystalline powder

Uses

Preparation of aluminum fluoride

Uses

preparation of pure aluminum fluoride.

Safety Profile

Poison by intravenous route. When heated to decomposition it emits very toxic fumes of F-, NOx, and NH3. See also ALUMINUM COMPOUNDS and FLUORIDES.

Synthesis

Freshly precipitated hydrated aluminum oxide is introduced portionwise into a hot, rather concentrated NH4F solution. A gelatinous precipitate results which settles easily when the solution is boiled down. The supernatant liquid is decanted or suctionfiltered, and the precipitate is washed with an alcohol-water solution and dried at 105°C.
