Vanadium processing |

Vanadium processing: 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

Vanadium

Vanadium (V) is a metal with a moderate specific gravity () and a relatively high melting point (1710° C). Vanadium is often considered to be an uncommon element, but its abundance in the earth's crust is actually comparable to that of copper, nickel, and zinc.
