Vanadium processing - Alloying, Extraction, Refining: 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 …
