Description
A ductile metallic element. Vanadium was discovered in 1803 by Andres del Rio, rediscovered in 1831 by Nils Selstrom, and isolated by Henry Roscoe in 1867. It has an abundance of 0.015% in the earth's crust and primarily occurs in the ores patronite, vanadinite, roscoelite, and carnotite. Vanadium is mined in Mexico, Peru, South Africa, Zambia, Italy, Germany, and the U.S. (Colorado, Utah, Arizona, New Mexico). The silvery white metal is primarily added to Steel to increase rust and wear resistance. Vanadium is also used as a target material for x-rays. Vanadium salts are used as yellow and red colorants in Glass and glazes, as UV absorbers, as mordants, and as photographic developers.
