White crystalline powder
[Uses]

Preparation of aluminum fluoride
[Uses]

preparation of pure aluminum fluoride.
[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.
