抄録

The electrolysis in the molten salt bath has been carried out for the extraction of titanium from the anode of TiO, TiC and Ti-C-O alloys which were obtained from titanium oxide or titanium slags by the carbon reduction in vacuum and arc. It was found that the extraction of titanium was possible at a low voltage below 1.5 V by the electrolysis from the anode with a mixture of TiO and C. In such a process, titanium contained 0.12∼0.52% carbon, 0.36∼3.05% oxygen and the extraction ratio of titanium from the anode was 55%.<BR>In case of the electrolysis using TiC as an anode, a better extraction ratio of titanium (about 70%) was obtained, of which the carbon content was considerably low. At the earlier stage, high purity titanium was obtained by the anode electrolysis from the crude titanium produced by the carbon arc reduction. At the latter stage, titanium was extracted from the anode by the same method as the anode electrolysis of TiC, TiO.<BR>The grade of titanium, deposited from the anode electrolysis of TiO, TiC and Ti-C-O alloys, was the same or better titanium in comparision with metals obtained from the electro-reduction of TiO2 in the molten salt bath of CaCl2.
