Abstract: A new process is proposed to reduce V2O5 by using calcium in molten CaCl2 for vanadium production. It consists of the calcium reduction in molten CaCl2 and the electrochemical reaction for the recovery of Ca from CaO in the same bath. V2O5 pellet was placed on cathode in order to react with Ca electrochemically generated near the cathode. V2O5 exists as liquid at the experimental temperature (1123 K), because of the melting point of 963 K for V2O5. At the initial stage of the reduction, liquid sample is reduced to solid CaV2O4. As the supplied quantity of electricity increased, the oxygen concentration in the vanadium samples decreased exponentially. Vanadium containing only 1800 ppm oxygen was obtained after the electrolysis for 34.4 ks.
