The low titanium aluminum alloy was prepared by molten salt electrolysis process using TiO2-containing carbon anode. The residual rates of TiO2-containing carbon anode in CO2 and in air atmosphere were tested, respectively, the TiO2-containing pitch cokes were tested by XRD, the morphology and composition of TiO2-containing carbon anode, initial aluminum and after electrolytic aluminum were analyzed by scanning electron microscope (SEM) and energy spectrum (EDS). The results show that the rate of residual of TiO2-containing carbon anode can also be significantly improved with increasing Ti content. When adding amount of TiO2 is 1%, the residual rate in CO2 sharply increases from 76.3% to 93.5%, and the residual rate in air increases from 51.87% to 65.92%. The TiO2 phase is unchanged during the process of preparing carbon anode. The TiO2-containing carbon anode can run stably in the electrolysis process. The TiO2 dissolves into electrolyte when the carbon anode is consumed, and the low titanium aluminum alloy is prepared.
