Vanadium is a hard early transition metal with variable oxidation states and strong affinity for oxygen, nitrogen, and carbon. It occurs mainly dispersed in minerals rather than as native metal. Its technological importance comes chiefly from alloying steel and from vanadium redox-flow batteries. Chemically it is notable for accessible +2, +3, +4, and +5 states, often producing distinctly colored ions and oxides.

Pure vanadium is a bright white metal, and is soft and ductile. It has good corrosion resistance to alkalis, sulfuric and hydrochloric acid, and salt water, but the metal oxidizes readily above 660°C.

The metal has good structural strength and a low fission neutron cross section, making it useful in nuclear applications.

The name derives from the Scandinavian goddess of love and beauty, Freyja Vanadis, because of its many beautiful multi-coloured compounds. Vanadium was discovered by the Swedish physician and chemist Nils-Gabriel Sefström in 1830.

Vanadium had originally been discovered by the Spanish mineralogist Andres Manuel del Rio y Fernandez in 1801, who named it erythronium, after the plant of that name whose flowers have many beautiful colours. Del Rio later decided that it was really chromium in his lead sample. Vanadium metal was first isolated by the English chemist Henry Enfield Roscoe in 1869.

Vanadium was discovered by Andrés Manuel del Rio, a Spanish chemist, in 1801. Rio sent samples of vanadium ore and a letter describing his methods to the Institute de France in Paris, France, for analysis and confirmation. Unfortunately for Rio, his letter was lost in a shipwreck and the Institute only received his samples, which contained a brief note describing how much this new element, which Rio had named erythronium, resembled chromium. Rio withdrew his claim when he received a letter from Paris disputing his discovery. Vanadium was rediscovered by Nils Gabriel Sefstrôm, a Swedish chemist, in 1830 while analyzing samples of iron from a mine in Sweden. Vanadium was isolated by Sir Henry Enfield Roscoe, an English chemist, in 1867 by combining vanadium trichloride (VCl3) with hydrogen gas (H2). Today, vanadium is primarily obtained from the minerals vanadinite (Pb5(VO)3Cl) and carnotite (K2(UO2)2VO4·1-3H2O) by heating crushed ore in the presence of carbon and chlorine to produce vanadium trichloride. The vanadium trichloride is then heated with magnesium in an argon atmosphere.

Named after Scandinavian goddess, Vanadis. Vanadium was first discovered by del Rio in 1801. Unfortunately, a French chemist incorrectly declared that del Rio's new element was only impure chromium. Del Rio thought himself to be mistaken and accepted the French chemists' statement.

The element was rediscovered in 1830 by Sefstrom, who named the element in honor of the Scandinavian goddess, Vanadis, because of its beautiful multicolored compounds. It was isolated in nearly pure form by Roscoe, who in 1867 reduced the chloride with hydrogen.

Vanadium of 99.3 to 99.8% purity was not produced until 1922.

Sources

Sources of this element.

Vanadium is found in about 65 different minerals among which are carnotite, roscoelite, vanadinite, and patronite, important sources of the metal. Vanadium is also found in phosphate rock and certain iron ores, and is present in some crude oils in the form of organic complexes. It is also found in small percentages in meteorites.

Commercial production from petroleum ash holds promise as an important source of the element. High-purity ductile vanadium can be obtained by reduction of vanadium trichloride with magnesium or with magnesium-sodium mixtures.

Much of the vanadium metal being produced is now made by calcium reduction of V2O5 in a pressure vessel, an adaption of a process developed by McKechnie and Seybair.
