Vanadium is a silver-gray rare metal that is refractory to melting and volatile. It has a combination of rigidity and softness, lively and changeable valence, and bright and colorful luster. High-purity vanadium is hard, non-magnetic, has good ductility, is not easy to oxidize, and is light in weight. When it is added to conventional metals to form alloys, it can significantly improve the plasticity, ductility, flexibility and strength of the alloy.
Vanadium has important applications in iron and steel industry, metallurgy and chemical industry, aerospace, national defense industry, medicine, pigment, glass, new energy battery and other fields. It is known as “metal vitamin”, “chemical bread” and “monosodium glutamate of modern industry”.
