Vanadium is an element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature.
Spanish-Mexican scientist Andrés Manuel del Río discovered compounds of vanadium in 1801 by analyzing a new lead-bearing mineral. Then in 1830, Nils Gabriel Sefström generated chlorides of vanadium, thus proving there was a new element, and named it “vanadium” after the Scandinavian goddess of beauty and fertility, Vanadís. The name was based on the wide range of colors found in vanadium compounds.
Del Rio's lead mineral was eventually called vanadinite for its vanadium content. In 1867 Henry Enfield Roscoe obtained the pure element.
Vanadium, crystal bar
Vanadium occurs naturally in about 65 minerals and fossil fuel deposits. It is mainly used to produce specialty steel alloys such as high-speed tool steels, and some aluminium alloys. The most important industrial vanadium compound, vanadium pentoxide, is used as a catalyst for the production of sulfuric acid.
Neither a Recommended Dietary Intake nor an Adequate Intake has been established. Dietary intake is estimated at 6 to 18 µg/day, with less than 5% absorbed. The Tolerable Upper Intake Level (UL) of dietary vanadium, beyond which adverse effects may occur, is set at 1.8 mg/day
