Niobium Metal is a silver-gray active metal with a molecular formula of Nb. Niobium metals are extremely stable in air at room temperature and do not interact with air. Although it has a higher melting point in the elemental state (2,468 ° C), its density is lower than other refractory metals. It also resists various types of erosion and forms a dielectric oxide layer. It does not react with hydrochloric acid, concentrated nitric acid and sulfuric acid under both cold and hot conditions. It can be used to Magnetic material, etc. It can also be used as an electrode, rectifier, and electrolytic capacitor of an electron tube. Medically used to make thin slices or thin lines, and to repair the damaged tissue. Although Tantalum is highly resistant to corrosion, its corrosion resistance is due to the formation of a stable Niobium pentoxide (Nb2O5) protective film on the surface.
