Abstract: | An alternative process of the reduction of V2O5 was studied. It consists of thermochemical and electrochemical reactions in molten CaCl2 + CaO. V2O5 is thermochemically reduced by Ca. The by-product CaO is electrolyzed. Liquid V2O5 was reduced to vanadium metal through intermediate CaV2O4, and oxygen concentration was 1860ppm at minimum. By deoxidation of the sample with a smaller specific surface area, the lowest oxygen concentration, 460ppm, could be achieved. A major component of ejected gas from the anode was CO2 at the initial stage and CO at the later stage. O2 gas was not detected because its concentration was lower than detection limit. |
