Niobium

Niobium

History

Element opened English scientist Charles Hatchet. Niobium metal was first obtained in 1866 the Swedish scientist Blomstrand recovery of chloride niobium hydrogen. In 1950, this element was finally approved by its name - niobium.

Nowadays

Niobium is the metal-superconductor. That is why his property is connected one of its major applications. But much more important is the composition of niobium alloys: the doping steel - increases the corrosion resistance of alloys with aluminum does not react to it with alkalis, with titanium, molybdenum and zirconium improves strength, heat resistance and heat-resistant, with the doping chromo-manganese was attached high endurance. Niobium yarns used in medicine in order to sew broken tendons, blood vessels and even nerves.
