Abstract

A cyclic process for producing aluminium fluoride comprises heating aluminium fluosilicate at temperatures up to 600 DEG C. to drive off silicon tetrafluoride, combining the latter with hydrofluoric acid, and utilizing the fluosilicic acid so obtained to produce aluminium fluosilicate from aluminium oxide or hydroxide to continue the cycle. The production of fluosilicate is effected at boiling temperature using excess of acid, and after cooling and separation from the mother liquor, the fluosilicate is dried below 40 DEG C. prior to its decomposition by heat. Substantially anhydrous aluminium fluoride is obtained, but it may, if desired, be reheated at temperatures between 100--600 DEG C. in an aluminium vessel.
