General

Vanadium is a medium-hard, ductile, steel-blue metal. It is harder than most metals and steels. Vanadium has good resistance to corrosion and it is stable against alkalis and sulfuric and hydrochloric acids. It is oxidized in air at about 933 K (660 ℃, 1220 ℉), although an oxide passivation layer forms even at room temperature. High-purity vanadium is used as a barrier in the integrated circuit to prevent diffusion between the gold conductive layer and the nickel bonding layer because vanadium have a high melting point and can withstand a large current density. Thus, the vanadium sputtering targets often used as the film material in integrated circuit. Some vanadium sputtering targets also as materials in surface coating. Besides, vanadium alloy targets (NiV) are widely used in solar film battery, electronic, semiconductor and construction glasses.
