摘要： A device and a method for preparing pure titanium by electrolysis-chlorination-electrolysis, wherein the device includes a first electrolytic cell, a second electrolytic cell, a chlorination reactor and guide tubes. The Cl2 generated at the anode of the first electrolytic cell is introduced into a chlorination reactor containing the TiCxOy or TiCxOyNz raw materials via a guide tube, and a chlorination is carried out to generate TiCl4 gas at a temperature of 200° C.-600° C. The TiCl4 gas passes through a guide tube into a cathode of the second electrolytic cell, and then an electrolysis is performed to obtain the high-purity titanium in the second electrolytic cell. At the same time, the Cl2 generated at the anode of the second electrolytic cell is recycled into the chlorination reactor in the first electrolytic cell to continue to participate in the chlorination of TiCxOy or TiCxOyNz.

摘要： A process is disclosed for the electro-refinement of titanium aluminides to produce titanium-aluminum master alloys which process is effective even in the presence of substantial amounts of aluminum and in the presence of ten (10) or more weight percent oxygen in the material(s) to be refined. The process is likewise effective without the addition of titanium chlorides or other forms of soluble titanium to the electrolyte bath comprising halide salts of alkali metals or alkali-earth metals or a combination thereof.

摘要： The present invention pertains to a method for removing a substance (X) from a solid metal or semi-metal compound (M1X) by electrolysis in a melt of M2Y, which comprises conducting the electrolysis under conditions such that reaction of X rather than M2 deposition occurs at a electrode surface, and that X dissolves in the electrolyte M2Y. The substance X is either removed from the surface (i.e., M1X) or by means of diffusion extracted from the case material. The temperature of the fused salt is chosen below the melting temperature of the metal M1. The potential is chosen below the decomposition potential of the electrolyte.
