• Uses: Niobium is a very important metal in both ferrous and nonferrous metallurgy. As an additive to alloys or when alloyed with other metals niobium imparts high mechanical strength, high electrical conductivity, and ductility to alloys. It enhances corrosion resistance of most alloys. The metal and several of its alloys exhibit superconductivity. Nobium is used as an additive in the manufacture of most high strength, low alloy carbon steels and microalloyed steels that are used in the construction of oil and gas pipelines, bridges, buildings, concrete bars, and automobiles. Nobium also is added to nickel- and cobalt-based superalloys and is a component of zirconium, titanium and tungsten alloys. Other applications of niobium are in electronic and propulsion devices, in electrodes; in catalysis; and in vacuum tubes and high-pressure sodium vapor lamps. Refined niobium metal is most useful as an alloy with other metals. It is used to producespecial stainless steel alloys, to make high-temperature magnets, as special metals for rocketsand missiles, and for high- and low-temperature–resistant ceramics. Stainless steel that hasbeen combined with niobium is less likely to break down under very high temperatures.This physical attribute is ideal for construction of both land- and sea-based nuclear reactors.Niobium has special cryogenic properties. It can withstand very cold temperatures, whichimproves its ability to conduct electricity. This characteristic makes it an excellent metal forlow-temperature electrical superconductors.Niobium alloyed with germanium becomes a superconductor of electricity that does notlose its superconductivity at 23.2° Kelvin as large amounts of electrical current are passedthrough it, as do some other superconductive alloys. In the pure metallic state, niobium wiresare also superconductors when the temperatures are reduced to near absolute zero (–273°C).Niobium alloys are also used to make superconductive magnets as well as jewelry.. In ferrous metallurgy: Ferroniobium (produced by silicon reduction of columbite) is used to alloy stainless steels and metals for welding rods. In niobium base alloys for high temperatures and nuclear reactions. Niobium has some use as a getter in electronic vacuum tubes. Niobium sputtering target is used in high temperature engineering products. It is also used as an alloying agent for certain steels where it greatly improves the strength of the resulting material. It is also finds applications in atomic reactors due to its corrosion resistance and, when combined with either tin (Nb3Sn) or zirconium, it has a high degree of superconductivity.
• Physical properties: Niobium is a soft grayish-silvery metal that resembles fresh-cut steel. It is usually found inminerals with other related metals. It neither tarnishes nor oxidizes in air at room temperaturebecause of a thin coating of niobium oxide. It does readily oxidize at high temperatures(above 200°C), particularly with oxygen and halogens (group 17). When alloyed with tin andaluminum, niobium has the property of superconductivity at 9.25 Kelvin degrees.Its melting point is 2,468°C, its boiling point is 4,742°C, and its density is 8.57 g/cm3.
