Abstract

The invention relates to a method of manufacturing calcined aluminum fluoride, AlF3, from aluminum fluoride hydrate, especially aluminum fluoride trihydrate, AlF3.3H2O, by drying and calcining. It is characterized in that (1) the hydrate is pre-dried or pre-calcined, (2) the pre-dried or pre-calcined hydrate is freed of the fine portion and (3) is totally dehydrated and calcined. The advantage of the method lies in the prevention of the adhesions on the walls of the calcining apparatus, which restrict transmission of heat, which hitherto made continuous operation impossible, and in the increase of the purity of the product produced. A variation of method lies in the fact the fine component arising from the second method step is prepared into a coarser material, possibly added again to the product of the second method step which is free of fine component, and according to the third step of the method is dehydrated and calcined.
