| titleOfInvention | Method for preparing high-purity metal vanadium powder by metal gas-based reduction |
| abstract | The invention relates to a method for preparing high-purity metal vanadium powder by metal gas-based reduction, belonging to the field of metal thermal reduction preparation of metal vanadium. The invention solves the technical problem that the existing process for producing high-purity metal vanadium is complex, and the prepared metal vanadium is not metal vanadium powder generally. The invention discloses a method for preparing high-purity metal vanadium powder by metal gas-based reduction, which comprises the steps of taking vanadium oxide as a raw material, taking active metal as a reducing agent, contacting the active metal with the raw material in a gas form to carry out thermal reduction reaction, and pickling, filtering and drying a reaction product to obtain the high-purity metal vanadium powder. The method is simple to operate, the flow is short, the purity of the prepared high-purity metal vanadium powder is more than or equal to 98%, the granularity range is 1-200 mu m, the surface of the metal vanadium powder particle is porous, and the method can be applied to the fields of powder metallurgy, 3D printing and the like. |
