A Study of Preparation of Titanium Metal by the Electrochemical Reduction of Titanium Dioxide in Molten Salt

Through the novel method in preparation of cathode, dehydration of molten salt etc, high purity of titanium (Ti) has been prepared by the electrochemical reduction of titanium dioxide (TiO2) .An investigation into the kinetics of the electrochemical reduction of TiO2 in molten calcium chloride (CaCl2) has been performed in according to electrochemical experiment. Partially reduced samples were prepared by terminating the reduction process after different reaction times and characterized by means of X-ray diffraction (XRD) analysis and chemical analysis.After analyzing, it is shown that the subsidiary reactions are the main reasons to affect the efficiency of current. Finally the methods to improve the efficiency of current have been provided.
