Vanadium has many excellent physical and chemical properties, so it is widely used, known as metal "vitamin". Most of the original vanadium is used in steel. The strength, toughness and wear resistance of steel are increased by refining the structure and grain size of steel and increasing the grain coarsening temperature. Later, people gradually found the excellent improvement effect of vanadium in titanium alloy, and applied to the aerospace field, which made the aerospace industry make a breakthrough. With the rapid development of science and technology, the requirements of new materials are increasing. Vanadium is more and more widely used in non iron and steel fields, covering aerospace, chemistry, battery, pigment, glass, optics, medicine and many other fields.
Steel industry
About 85% of vanadium is added to steel production in the form of ferrovanadium and vanadium nitrogen alloy 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, rails, etc. Vanadium bearing 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 steel strip; reinforced bar for construction; high carbon steel wire rod; rail; tool and die steel, etc.
Aerospace Industry
Vanadium titanium alloy is widely used in aircraft engine, aerospace cabin frame, missile, hydrofoil and introducer of warship, steam turbine blade, rocket engine shell, etc. In addition, vanadium alloys are also used in magnetic materials, cemented carbide, superconducting materials and nuclear reactor materials.
Chemical industry
In chemical industry, vanadium compounds are used as catalysts, ceramic colorants, developers, desiccants and raw materials for producing high-purity vanadium oxide or ferrovanadium. V205 as catalyst has special activity, which is difficult to be replaced by other elements.
Pigment, glass
Vanadium salts are colorful, including green, red, black and yellow. These colorful vanadium compounds are made into bright pigments: if added to glass, they can be made into colored glass, and can also be used to make various inks.
Battery industry
VRB is the most promising large capacity energy storage system. Compared with other batteries, it has the following points: (1) the rated power and rated energy are independent, the power depends on the battery stack, and the energy size depends on the electrolyte, so the electrolyte can be increased at will to increase the battery capacity; (2) during charging and discharging, the vanadium battery is only liquid-phase reaction, which is not complex in the current of the battery, which is not as complex as the ordinary battery The solid state change of the broken or short circuit; (3) the battery has a long storage life; 4) it can discharge 100% without damaging the battery;
The field of Optics
Due to their unique phase transition characteristics, vanadium dioxide thin films and ultrafine powders can be widely used in electrical and optical switching devices, solar control materials, optical disk dielectric materials, coatings, thermistor and other fields;
Pharmaceutical industry
Vanadium can regulate the blood sugar of human body and has the effect of anti diabetes. In addition, vanadium can improve myocardial function and has obvious therapeutic effect on hypertension. At the same time, vanadium can significantly improve kidney swelling, reduce urinary protein and improve renal function.
