Electrodeposition of Titanium from Molten Chloride Electrolytes by Using Titanium Oxycarbide Anodes
The use of an anode consisting of titanium oxycarbide combined with a liquid cathode is a promising approach to produce pure titanium. This approach was studied in order to overcome problems related to carbon contamination and also possibly to reduce the influence of disproportionation reactions involving various oxidation states of titanium. Titanium deposits were obtained titanium cathodes during electrolysis in molten equimo-lar NaCl-KCl with additions of TiCl3 at 800-8501. The deposits were contaminated by carbon and oxygen, probably due to the transport of CO from the anode to the cathode. Some experiments were conducted by using a liquid cathode of Zn,Sn or Bi. In all these experiments dissolved Ti (Ⅲ)species and CO were formed by oxidizing the oxycarbide anode.
