Preparation of Vanadium Metal by Molten Salt Electrolysis

Vanadium metal was prepared by molten salt electrolysis method using vanadium oxide as raw material.The influence of electrolysis parameters such as electrolysis temperature,electrolysis voltage,electrolysis time and the area of anode on electrolysis current was studied.Scanning electro microscope image,microanalysis and X-ray diffraction were used to characterize the composition,structure and morphology of specimens which were incompletely and completely reduced.Vanadium was obtained in the lab-scale production under the temperature of 850~900 ℃ and voltage of 2.9~3.0 V.Due to its short process flow and low temperature and simple equipment requirements,this method exhibits advantages in small scale production of vanadium.
