Vanadium processing | Extraction, Uses & Applications | Britannica

vanadium processing, preparation of the metal for use in various products Vanadium (V) is a grayish silver metal whose crystal structure is a bodycentred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F) The metal is used principally as an alloying addition to highstrength lowalloy (HSLA) steels and, to a lesser extent, in tool steels and iron andThere is evidence that meteorites were used as a source of iron before 3000 bc, but extraction of the metal from ores dates from about 2000 bc Production seems to have started in the copperproducing regions of Anatolia and Persia , where the use of iron compounds as fluxes to assist in melting may have accidentally caused metallic iron toIron processing | Definition, History, Steps, Uses, & Facts
