Abstract
823,125. Electrolytic production of titanium, zirconium, and hafnium. HORIZONS TITANIUM CORPORATION. July 1, 1957 [July 9, 1956], No. 20688/57. Class 41. A method of producing refined and ductile metallic titanium having a Brinck Hardness number of less than 120, comprises passing an electric current through an electrolytic cell having an anode and a cathode and a molten salt electrolyte consisting essentially of at least one alkali metal halide and at least one alkali metal fluotitanate; disposing impure titanium metal so that it is in contact with the anode and with a sludge formed by impurities during refining; and maintaining an anode current density and voltage sufficient to deposit purified titanium metal at the cathode but insufficient to liberate any halogen gas at the anode or to dissociate any of the sludge. Sodium chloride or any other alkali metal halides may be used either alone or as mixtures. Specified alkali metal fluotitanates are sodium and potassium fluotitanates. The electrolytic cell may be made of graphite, nickel, iron or stainless steel; and it may be provided with means for maintaining an inert atmosphere in the cell. The cell container may serve as the anode. Examples describe electrolysis of a melt containing sodium chloride and potassium fluotitanate. Zirconium and hafnium may be purified in a similar manner by replacing the fluotitanate by alkali metal double fluorides of these metals. Specifications 701,289, 728,523, 736,567 and 743,695 are referred to.
