Vanadium is a soft, shiny, silvery metal that is found in many different minerals, including crude oils. It occurs in the earth's crust with a frequency of 160 ppm and can be isolated with aluminum after conversion into the pentoxide V2O5 and subsequent reduction. High-purity vanadium can be obtained in the Van Arkel process, in which the iodide is thermally decomposed on a hot metal wire. Pure vanadium is corrosion-resistant due to the protective oxide layer on its surface; it is attacked by concentrated acids, but not by molten alkalis.
