Vanadium demand for use in rebar (reinforcing steel used as rods in concrete) continues to increase at 6% annually. New markets are emerging and scaling up. These markets will increase vanadium demand further as it becomes more widely used in automotive, aviation, aerospace, renewable energy, power lines and pylons. ...
Vanadium is a chemical element; it has 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.
