Synthesis of Vanadium Powder by Magnesiothermic Reduction

Abstract:

Vanadium metal powder was successfully synthesized by combination reduction process with hydrogen gas and liquid magnesium. V₂O₅ as a raw material was first reduced by hydrogen gas to produce V₂O₃ at 873K for 3 hours and then it was reduced by liquid magnesium at 1,073K for 48 hours to become final vanadium powder. The microstructure and chemical composition of pure vanadium powder fabricated were examined by SEM(Scanning Electron Microscopy) and EDX(energy dispersive spectroscopy), respectively. The oxygen content of vanadium powder was finally found to be 0.5 wt.% showing the structure loosely agglomerated with fine particles of about 1~2μm.
