Processing of vanadium: a review
Vanadium was named after the Norse goddess Vanadis which represented beauty and fertility. The appellation was selected since the element's beautiful colours are used as a dye for the manufacture of pottery and ceramics (Vanadium, 2003).The element was first discovered in 1801 within a lead vanadate ore by a Mexican, Andrés Manuel del Rio, but it was mistaken …

Vanadium and its compounds
Vanadium is a rare, weak, and viscous transition metal, with a total of 31 isotopes, including one stable one (51 V). The term "vanadium" is derived from the name of the beautiful goddess Venus (or Vanadis). In 1801 Spanish mineralogist A.M. del Rio discovered vanadium in lead ores and misnamed it as a compound of chromium.

vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.
