'''Vanadium''' is a silvery metal that resists corrosion.
==History==
Vanadium was actually discovered twice. The first time was in 1801 by a Professor of Mineralogy in [[Mexico City]], named Andrés Manuel del Rio. He found it in a specimen of vanadite, Pb<sub>5</sub>(VO<sub>4</sub>)<sub>3</sub>Cl. The second time vanadium was discovered was in 1831 by the Swedish chemist Nil Gabriel Selfström at [[Stockholm]]. He separated it from a sample of cast [[iron]] made from ore.<ref>http://www.rsc.org/periodic-table/element/23/vanadium</ref>
Henry Roscoe showed that these previous samples of the metal were really vanadium nitride (VN) and produced pure vanadium was in 1869.<ref>http://www.rsc.org/periodic-table/element/23/vanadium</ref>
==Uses==
===Industrial===
Vanadium pentoxide is used as a [[catalyst]] to make [[sulfuric acid]]. [[Vanadate]], another compound of vanadium, protects steel from rust and corrosion. Vanadium dioxide is used to make glass coatings which block [[infrared radiation]]. Other vanadium compounds are used for fake jewelry and [[Superconductivity|superconducting]] [[magnets]].<ref>http://wanttoknowit.com/uses-of-vanadium/</ref>
===Medical===
Along with [[chromium]], Vanadium is one of the minerals which is believed to help control blood sugar. It is sometimes used for [[diabetes]] in place of animal insulin injections.<ref>http://www.whale.to/a/diabetes_shame.html</ref> However, there has been no official study to discover how much vanadium is required by the human body, so many conventional doctors avoid suggesting this supplementation.<ref>http://umm.edu/health/medical/altmed/supplement/vanadium</ref>
