Vanadium is named for the Scandinavian goddess Vanadis and was first discovered in 1801. It was isolated in its pure form in 1927. Vanadium is found in about 65 different minerals among which are carnotite, roscoelite, vanadite and patronite. Vanadium is also found in some phosphate rock and certain iron ores, and is present in some crude oils in the form of organic complexes. High purity, ductile vanadium can be obtained by reduction of vanadium trichloride with magnesium or magnesium-sodium mixtures. 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 waters. Vanadium is used in making rust resistant, spring and high speed steel tools. It is an important carbide stabilizer in making steels. About 80% of the vanadium produced is used as ferrovanadium or as a steel additive.
