Abstract

Anhydrous zirconium tetrafluoride is produced by a process comprising (1) heating an aqueous solution of zirconium fluoride containing hydrofluoric acid at 120-170 DEG C. until it is sensibly dry and (2) calcining the dried product at between 300 DEG C. and its sublimation temperature. In the preferred method zirconium oxide is subjected to the action of sufficient 30-70 per cent. by weight aqueous hydrofluoric acid to provide 4.2-4.4 mols of HF per mol of zirconium oxide at 60-80 DEG C. for 4-6 hours; the resulting products are heated to dryness at 140-160 DEG C. and calcined at 300-350 DEG C. for 4-5 hours. Examples are given in which zirconium oxide and zirconyl chloride are used as sources of zirconium.
