Niobium - Element information, properties and uses Periodic Tabl

Around that time, there was considerable confusion about the difference between this element and the closely related tantalum. This confusion was not resolved until 1846 by Heinrich Rose and Jean Charles Galissard de Marignac, who rediscovered the element. Rose was unaware of Hatchett's work and gave the element a different name, niobium. In 1864, Christian Blomstrand was the first to prepare the pure metal, reducing niobium chloride by heating it in a hydrogen atmosphere. The element is never found as a free element but does occur in the minerals columbite ((Fe,Mn)(Nb,Ta)2O6), columbite-tantalite or coltan ((Fe,Mn)(Ta,Nb)2O6), pyrochlore ((Na,Ca)2Nb2O6OH,F), and euxenite ((Y,Ca,Ce,U,Th)(Nb,Ta,Ti)2O6). Minerals that contain niobium often also contain tantalum. Large deposits of niobium have been found associated with carbonatites (carbon-silicate igneous rocks) and as a constituent of pyrochlore. Brazil and Canada are the major producers of niobium mineral concentrates and extensive ore reserves are also in Nigeria, Democratic Republic of Congo, and Russia. Niobium metal is a rare, soft, grey material, which, when exposed to air, quickly forms a protective oxide Niobium metal is not used widely, one application is as additive to superalloys, which have to.. Solid metal does not ignite. However, high surface area material such as 5-micron powder may undergo auto-ignition at room temperature that could be extinguished with dolomite, sand, sodium chloride, or soda ash.

Niobium, due to its variety of properties, is used in several areas of research. One such research is in creating magnets. One of the strongest superconducting magnets in the world uses niobium alloy wires, such as niobium-tin and niobium-titanium, according to National High Magnetic Field Laboratory. The 2.3-ton magnet is made of coils of three types of wire, two with niobium, and reaches field strengths of 32 teslas (the strength of Earth's magnetic field on the surface of the planet ranges from 30 to just over 60 microteslas or 30x10-6 to 60x10-6 teslas).An integrated supply risk index from 1 (very low risk) to 10 (very high risk). This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.A measure of how difficult it is to compress a substance. It is given by the ratio of the pressure on a body to the fractional decrease in volume.

Learn more about its Chemical, Physical properties, uses, facts and more with Byju's Another confusion related to its finding arose in 1844 when Heinrich Rose, a German mineralogist, and chemist, used samples of columbite and tantalite to produce two new acids, niobic and pelopic that were believed to be similar to each other. It was resolved after twenty-two years by a Swiss Chemist called Jean Charles Galissard de Marignac who proved that the newly isolated acids were from two different elements. Then in 1864, Blomstrand finally isolated metallic niobium by heating niobium chloride with hydrogen [1, 3].Covalent radiusHalf of the distance between two atoms within a single covalent bond.

Later in 1809, Charles Hatchett, an English Chemist, while analyzing the same mineral, found a different element in it that was named columbium, but couldn’t be isolated. A new twist in the discovery of niobium took place in 1809 when the English chemist and physicist William Hyde Wollaston compared the mineral with another mineral called tantalite and announced that columbium was actually the element tantalum.A measure of how difficult it is to deform a material.

Niobium Planse

The pure metal is soft and ductile; it looks like steel or, when polished, like platinum. Although it has excellent corrosion resistance, niobium is susceptible to oxidation above about 400° C (750° F). Niobium can best be dissolved in a mixture of nitric and hydrofluoric acids. Completely miscible with iron, it is added in the form of ferroniobium to some stainless steels to give stability on welding or heating. Niobium is used as a major alloying element in nickel-based superalloys and as a minor but important additive to high-strength, low-alloy steels. Because of its compatibility with uranium, resistance to corrosion by molten alkali-metal coolants, and low thermal-neutron cross section, it has been used alone or alloyed with zirconium in claddings for nuclear reactor cores. Cemented carbides used as hot-pressing dies and cutting tools are made harder and more resistant to shock and erosion by the presence of niobium. Niobium is useful in constructing cryogenic (low temperature) electronic devices of low power consumption. Niobium-tin (Nb3Sn) is a superconductor below 18.45 Kelvins (K), and niobium metal itself, below 9.15 K.This shiny gray, ductile metal takes on a bluish tinge when exposed to air at room temperature for extended periods. When it is processed at even moderate temperatures, it must be placed in a protective atmosphere. The metal begins to oxidize in air at 200° C. Its most common oxidation states are +3, and +5, although others are also known.

  1. The element was called columbium (symbol Cb) in the United States for about 100 years, while it was called niobium in Europe. In 1949, the International Union of Pure and Applied Chemistry compromised and officially adopted niobium as the element's name, in deference to European usage. In turn, the union accepted tungsten rather than wolfram as the name for Element No. 74 (which still carries the symbol W), in deference to American usage. Many metallurgists and metal societies, however, still refer to niobium as columbium.

This was a compromise of sorts; the IUPAC accepted tungsten instead of wolfram, in deference to North American usage; and niobium instead of columbium, in deference to European usage. Not everyone agreed, and while many leading chemical societies and government organizations refer to it by the official IUPAC name, many leading metallurgists, metal societies, and most leading American commercial producers still refer to the metal by the original "columbium."

Niobium was first discovered (1801) in an ore sample from Connecticut by the English chemist Charles Hatchett, who called the element columbium in honour of the country of its origin, Columbia being a synonym for the United States. In 1844 a German chemist, Heinrich Rose, discovered what he considered to be a new element occurring along with tantalum and named it niobium after Niobe, the mythological goddess who was the daughter of Tantalus. After considerable controversy it was decided that columbium and niobium were the same element. Eventually international agreement (about 1950) was reached to adopt the name niobium, though columbium persisted in the U.S. metallurgical industry.

Niobium is a transition metal that lies in period 5 of the periodic table, between zirconium and molybdenum. It is also located in group 5 (former group 5B), between vanadium and tantalum. Its chemical properties are almost identical to those of tantalum.

Compounds of niobium are of relatively minor importance. Those found in nature have the +5 oxidation state, but compounds of lower oxidation states (+2 to +4) have been prepared. Quadruply charged niobium, for example, in the form of the carbide, NbC, is used for making cemented carbides. Niobium is a transition metal in Group 5 (VB) of the periodic table.
