Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...

Vanadium processing - The metal and its alloys | Britannica

Vanadium processing - Vanadium processing - The metal and its alloys: In its pure form, vanadium is soft and ductile. It can be fabricated into mill forms, but it oxidizes readily at temperatures above 663° C (1,225° F) and is liable to pick up interstitial impurities. Because the metal has good corrosion resistance to liquid metal, a low absorption of neutrons, and a short half-life in its ...
