The anodic dissolution behavior of conductive titanium oxycarbide in NaCl-KCl melt was investigated in detail. An emphasis is on the anode gas was analyzed on-line using mass spectra when performing electrolysis. The results showed that TiCxOy can dissolve in alkali chloride melt During the anodic dissolution, titanium component of TiCxO y dissolves as Ti2+ ion into the molten salt, and the components of carbon and oxygen form carbon monoxide (CO) simultaneously. A series of investigation has been focused on the influences of the current density and the concentration of Ti2+ on the anodic dissolution. An interesting result shows that the faradic dissolution ratio is significantly related to the anodic current density instead of the concentration of Ti 2+.
