 Abstract
 PDF
- The extraction of metallic pure vanadium powder from raw oxide has been tried by Mg-reduction. In first stage, V_2O_5 powders as initial raw material was reduced by hydrogen gas into V_2O_3 phase. V_2O_3 powder was reduced in next stage by magnesium gas at 1,073K for 24 hours. After reduction reaction, the MgO component mixed with reduced vanadium powder were dissolved and removed fully in 10% HCl solution for 5 hours at room temperature. The oxygen content and particle size of finally produced vanadium powders were 0.84 wt% and 1 µm, respectively
