Vanadium metal (V)-Foil

Vanadium metal (V)-Foil introduce:

Characteristic

 

Vanadium is a chemical element with the atomic number 23. It is a hard, silvery-grey, ductile, malleable transition metal. The elemental metal is rarely found in nature.Vanadium melting point is very high, often with niobium, tantalum, tungsten, molybdenum and difficult melting metal.Has the ability to resist hydrochloric acid and sulfuric acid, and in the resistance to gas, salt, water corrosion performance is better than most stainless steel.

Application

 

It is mainly used to produce specialty steel alloys such as high-speed tool steels. The most important industrial vanadium compound, vanadium pentoxide, is used as a catalyst for the production of sulfuric acid. The vanadium redox battery for energy storage may be an important application in the future.
