Abstract

Titanium oxycarbide (TiC xO y) was successfully prepared by an electro-deoxidation of TiO 2/C composite cathode in molten calcium chloride at 900 °C. The composite cathode was prepared by adding an amount of carbon into TiO 2 powders. By using X-rays diffraction and scanning electron microscopy, it was found that the presence of carbon resulted in changes in reaction mechanism and accelerated the rate of electrochemical reaction. The results suggested that the electrochemical reduction of TiO 2/C composite was the following: firstly titanium dioxide was reduced to TiO n (0 < n < 1) along with the formation of CaTiO 3. Then, TiO n (0 < n < 1) reacted with carbon to TiC xO y.
