Vanadium is a chemical element with the symbol V and atomic number 23.


Steel Alloys: The most common use of vanadium is in high-strength, low-alloy (HSLA) steels. Vanadium increases the strength, toughness, and wear resistance of steel, making it ideal for construction, tools, and automotive components. Titanium Alloys: Vanadium is used in titanium alloys for aerospace applications, as it improves the strength-to-weight ratio of titanium. This is especially important in jet engines, aircraft, and space vehicles. Catalysts: Vanadium pentoxide (V₂O₅) is used as a catalyst in the production of sulfuric acid, one of the most important industrial chemicals. It is also used in other chemical processes, including in the production of certain plastics and as a catalyst in petroleum refining. Batteries: Vanadium is used in vanadium redox flow batteries (VRFBs), which are emerging as a promising technology for large-scale energy storage. These batteries offer long life cycles and the ability to store large amounts of energy, making them suitable for renewable energy applications like wind and solar power. Pigments: Vanadium compounds are used in the production of dyes and pigments, especially yellow, orange, and red colors in ceramics and glassmaking.
