In 1830, N. Sefström discovered vanadium in some iron ores. Vanadium is a white metal that possesses good resistance to corrosion by alkalis, and sulphuric and hydrochloric acid. Vanadium occurs in approximately sixty-five different minerals and in carbon deposits such as crude oil, coal, oil shale and tar sands, but is never found unbound in nature. Because vanadium has substantial component strength, low fission neutron cross section, and oxidizes freely at about 933 K, it is a useful component in nuclear applications. Vanadium’s main application is used as ferrovanadium or as a steel supplement. Vanadium is also manufactured in steel alloys such as stainless steel instruments and tools, electrical fuel cells and storage batteries, and is mixed with aluminum in titanium alloys for aircrafts.
