Introduction of vanadium

    Vanadium is an amazing metal, 1831 by the Swedish chemist Sefstrom found in iron ore, prices of its various oxidation states of the compounds have a beautiful color, colorful, so beautiful goddess of the Swedish Savannah Andean (Vanadies) named vanadium.    Vanadium chemical symbol V, the atomic number 23, atomic weight 50.942, a melting point of 1887 ° C, boiling point 3337 ° C.Classification are rare in metallurgy high melting point metal.
    Vanadium is a pure silver-white slightly blue, body-centered cubic structure.Vanadium in abundance in the earth's crust is about 0.02%, compared with copper, zinc, nickel, chromium are higher.However, there is a characteristic of vanadium metal, it is difficult to form independent deposits associated is very obvious, so very decentralized in nature, usually associated with other metals, such as: V-Ti magnetite.Therefore, not easy to separate the vanadium mining and metals refining.         
Vanadium has a ductility; contains oxygen, nitrogen, hydrogen, when the brittle, hard.Vanadium at higher temperatures and smaller non-metallic atomic weight to form a stable compound; at low temperatures with good corrosion resistance.Vanadium into the alloy after the alloy can enhance the strength, lower coefficient of thermal expansion.Currently a major source of vanadium is in Australia, South Africa, Russia and China, and to rely on the recovery of vanadium from oil residue and other countries.
