Vanadium Product Introduction
Vanadium is a high melting point refractory rare metal, and its main product forms are: vanadium pentoxide, vanadium trioxide, ferrovanadium, vanadium nitride, etc. Among them, vanadium pentoxide and vanadium trioxide are the most important vanadium oxides in actual production, and they are the main raw materials for the preparation of subsequent vanadium products such as ferrovanadium, vanadium nitride and vanadium carbide.
Fields of application of vanadium
Vanadium is an important alloying element mainly used in the steel industry. Vanadium-containing steel has excellent properties such as high strength, high toughness and good wear resistance, so it is widely used in machinery, automobile, shipbuilding, railway, aviation, bridge, electronic technology, national defense industry and other industries.
Vanadium can be used as a stabilizer and strengthening agent in titanium alloys, which makes titanium alloys have good ductility and plasticity. In addition, vanadium is mainly used in the chemical industry as a catalyst and a colorant. Vanadium is also used to produce rechargeable hydrogen batteries or vanadium redox batteries.
About 85% of metallic vanadium is added to steel production in the form of ferrovanadium and vanadium-nitrogen alloys to improve the strength, toughness, ductility and heat resistance of steel. Vanadium-containing high-strength alloy steel is widely used in the production and construction of oil/gas pipelines, buildings, bridges, and rails. Vanadium-containing high-strength alloy steel mainly includes: high-strength low-alloy (HSLA) steel (comprehensive); HSLA steel plate; HSLA section steel; HSLA strip steel; advanced high-strength strip steel; and die steel, etc.
8-10% of metal vanadium is used in the form of titanium-aluminum-vanadium alloy in aircraft engines, aerospace cabin skeletons, missiles, steam turbine blades, rocket engine casings, etc. In addition, vanadium alloys are also used in magnetic materials, hard alloys, superconducting materials and nuclear reactor materials.
In the chemical industry, vanadium is mainly used as a catalyst for the manufacture of sulfuric acid and vulcanized rubber, and is also used to suppress the production of nitrous oxide in power plants. Other chemical vanadium products are mainly used in catalysts, ceramic colorants, developers, desiccants, etc.
