Vanadium (Jessica Horn)

  1. 1. By Jessica Horn Chemistry 120 Dr. Walters
  2. 2.  The element Vanadium is named after Vanadis, the Scandinavian goddess of Beauty because the element has beautiful multi-colored chemical compounds. Vanadium was originally discovered by the Spanish mineralogist Andres Manuel del Rio at Mexico City in 1801. He prepared salts from the mineral vanadinite (then called brown lead) but did not isolate the pure metal. Rediscovered by Nils Sefstrom of Sweden in 1830. Metallic vanadium was first isolated by Henry E. Roscoe in 1867, by reducing vanadium chloride (VCl3) with hydrogen.

  4. 4.  Symbol of Element : V Atomic Number of Vanadium : 23 Atomic Mass: 50.9415 amu Melting Point: 1890.0 °C - 2163.15 °K Boiling Point: 3380.0 °C - 3653.15 °K Crystal Structure: Cubic Density @ 293 K: 5.8 g/cm3 Color of Vanadium : bright white Vanadium is solid at room temperature.
  5. 5.  Vanadium has good structural strength It possesses good corrosion resistance to alkali metal, sulfuric acid, hydrochloric acid and salt water It oxidizes readily at temperatures greater then 660°C
  6. 6.  There are two naturally occurring isotopes -vanadium- 50 and vanadium-51. Vanadium-51 is much more common, making up about 99.75 percent of all naturally occurring vanadium. Other Isotopes include V-48 Half Life of15.98 days V-49 Half life 337.0 days V-50 Half Life of1.4E17 years V-51 Stable V-52 Half Life of 3.76 minutes
  7. 7.  Cost, pure: $220 per 100g Cost, bulk: $2.70 per 100g Vanadium is not found free in nature but is found combined in about 65 different minerals. Vanadium is also found in bauxite and in fossil fuel deposits. Commercially, production of the metal is by calcium reduction of the pentoxide.
  8. 8.  The main use of vanadium is to make alloys, especially with steel. When a small amount of vanadium is added it increases strength, toughness, and heat resistance. Vanadium steel alloys are used in gears, axles and crankshafts. It is also made into ferrovanadium, a vanadium-iron alloy. This form of vanadium is used in surgical instruments
  9. 9.  Titanium-aluminum-vanadium alloy is used in jet engines and for high-speed aircraft. Vanadium foil is used to cover titanium to bond it with steel. Vanadium-gallium tape is used in superconducting magnets. Vanadium pentoxide is used in ceramics and as a catalyst for the production of sulfuric acid. Vanadium pentoxide is also a potential new source of battery power.
