Electrolytic Preparation of Vanadium from V2c-type Carbide.
NTIS: PB 198 286 :17 pages
An electrochemical process was developed for the preparation of vanadium from vanadium carbide. Commercially available vanadium carbide (v2c) was used as the starting material. Vanadium was obtained by electrolysis of the v2c in a bacl2-kcl-nacl-vcl2 electrolyte at 670 deg c. Using a helium-atmosphere, molten-salt electrolytic cell. Vanadium products were recovered with purities as high as 99.6 percent. Current efficiencies of 87 percent and vanadium recoveries of 84 percent were attained. The cathode products were amenable to electrorefining to high-purity vanadium of 99.96-percent purity.
