In my country, about 90% of vanadium is used in the iron and steel industry. The application of vanadium in steel is mainly to improve its strength and toughness by adding vanadium. Adding 0.1% vanadium to structural steel can increase the strength by 10%-20%, reduce the weight of the structure by 15%-25%, and reduce the cost by 8%-10%.
Vanadium steel has the characteristics of high strength, toughness, wear resistance, and corrosion resistance, and is widely used in the construction of oil (gas) pipelines, buildings, bridges, rails, and pressure vessels. In 2000, the application amount of vanadium steel in my country reached 1.2 million t/a, and the application amount of vanadium-containing steel has increased by 10% annually.
Vanadium and titanium form important metal alloys Ti-6AI-4V, which are used in aircraft engines, aerospace cabin skeletons, missiles, hydrofoils and introducers of warships, steam turbine blade rocket engine casings, etc. In addition, vanadium alloys are also used in magnetic materials, hard alloys, superconducting materials (such as V, Ca), and nuclear reactor materials. The domestic producers of vanadium-aluminum master alloys include Baoji Nonferrous Metals Processing Plant and Jinzhou Ferroalloy Plant. The domestic output of vanadium-aluminum alloys cannot fully meet domestic needs, and some of them need to be imported from abroad every year. The market potential of vanadium-aluminum master alloys is quite large.
The main vanadium products used in the chemical industry are deep-processed products V205, (98%-99.99%), NH4VO3 (ammonium metavanadate), NaVO3 and KVO3, etc. They are respectively used in catalysts, ceramic colorants, developers, desiccants, and raw materials for the production of high-purity vanadium oxide or ferrovanadium. As a catalyst, V205 has special activity, and it is difficult to replace the element. Domestic powdery V2O5 is mainly extracted from stone coal. Due to the small scale and low output of domestic-related enterprises, it is difficult to produce high-end products. Therefore, this part of high-end products is mainly solved by imports.
The colors of vanadium salts are colorful, including green, red, black, yellow, and so on. For example, the divalent vanadium salt is often purple; the trivalent vanadium salt is green, the tetravalent vanadium salt is light blue, the basic derivatives of the tetravalent vanadium are often brown or black, and the vanadium pentoxide is red. These colorful vanadium compounds are made into bright pigments, such as adding to glass to make colored glass and can also be used to make various inks. In addition, vanadium dioxide thin films and ultrafine powders can be widely used in electrical and optical switching devices, solar control materials, optical disc dielectric materials, coatings, thermistors, and other fields due to their unique phase change characteristics; Beijing Shuoguang Tejing Technology Co., Ltd. has developed a yttrium vanadate crystal material for long-distance optical fiber communication. It has high birefringence, a high pass rate, and good light transmittance.
