| Abstract Scope |
An assessment of the preparation of vanadium has been performed based on a literature review. There are many treatments for preparation of vanadium at present, such as vacuum-aided carbothermal reduction process, silicothermic reduction process and so on. Those treatments inevitably exist its own preponderances and defects, but the aluminothermy reduction process has the most application due to the high purity product and low cost. According to the literature that the vanadium is very strong affinity for oxygen, which need a strong reductant to destroy it. In other word, the reduction ability of reductant is the most important parameter in vanadium production. Therefore, the core issue of vanadium smelting is to select an appropriate reductant, whose reductive ability is enough to reduce the O content in V-O solid solution to sufficiently low. Aiming at the above issues, this paper finally proposed a possibility for a new method to prepare vanadium. |
