Niobium (Nb) — 41st element of periodic table of D. I. Mendeleev. Atomic weight 93.986, melting point 2741 °K, boiling point 5015 °K. It’s brilliant grayish-silver metal with body-centered cubic crystal lattice of form α-Fe, а = 0.3294 nm.
Niobium production is growing rapidly, due to organic combination of its properties such as small thermal neutron capture cross section, refractoriness, ability to form heat-resistant and superconducting alloys, getter properties, corrosion resistance, low electron work function, excellent hot and cold pressure workability and weldability. Main areas of use of niobium: space and aviation technology, military-industrial complex, electronics, radio engineering, nuclear energy and industrial chemistry.
This metal is quite expensive. Niobium metal dust is flammable and irritating to skin and eyes. Some of its compounds are very toxic. MAC of niobium is 0.01 mg/l. When ingested, this element causes severe neuritis and subsequent limb paralysis.
Pure niobium and its alloys are used to manufacture aircraft and rocket parts; shells for plutonium and uranium atomic boilers (niobium carbide, melting point 3480 ° С), containers for metals in liquid state. Liquid potassium and sodium used as heat carriers in atomic reactors move through niobium tubes. Niobium is characterized by low induced (artificial) radioactivity, from which they make containers for storing radioactive waste. It is in demand in production of electrolytic capacitors; «hot» fittings of powerful generator and electron tubes and (cathodes, anodes, grids, etc.). Corrosion resistant equipment in chemical industry is made from niobium alloys. Non-ferrous metals alloy them, among others — uranium. Niobium found application in cryotrons — superconducting components of computers. It is also well known for being used in accelerating structures of andron collider.
