Abstract
A process for the electrolytic deposition of titanium of more than 99% purity or titanium alloys containing more than 99% metal comprises electrolyzing a fused bath containing BaBr2, MgBr2, NaBr, CaCl2 and a mixture of di- and tri-valent titanium bromides at a temperature of 400-500 DEG C., the current fluctuating (the frequency of the intermittent current component being 1500-8000 cycles per minute) the cell voltage being at least 1.0 volt and the cathode current density being at least 6 amp./ dm.2. The salt bath is regenerated by heating to between 500 and 600 DEG C. and the fluctuating current may be an alternating current superimposed on a direct current. The salt mixture for use in the process of the invention contains 3 parts NaBr, at least 2 parts BaBr2, 2-4 parts MgBr and 0.2-0.6 of the above amount of CaCl2, these components constituting at least 90% of the bath, with or without 3 parts of CsCl2, 2 parts MgCl2 and 2 parts of NaCl up to 5/6 of the CsCl2 being optionally replaced by a mixture having a composition near the eutectic of LiCl and KCl. [All parts are given as a molar ratio]. In the examples the salt bath is heated in two parts of a vertical apparatus so that the lower portion is at 500-600 DEG C. and the upper portion where the deposition is carried out is at 400-500 DEG C. The divalent titanium bromide in the bath may be introduced by reducing some of the tri-bromide with metallic titanium or by an electrolytic method in a diaphragm cell.
