    Sigma-Aldrich offers a number of Niobium products. View information & documentation regarding Niobium, including CAS, MSDS & more. Niobium was discovered in by Charles Hatchett. Its name comes from the Greek name Niobe, meaning “daughter of Tantalus” (tantalum is closely related to niobium in the periodic table of elements). Because the niobium was discovered in an ore called columbite, it was known temporarily as columbium.. Niobium, a gray or silvery soft metal, is ductile and very malleable at room temperature.

Niobium is considered to be a critical and strategic commodity because of the metal’s specialized applications in defense, energy, high-tech industrial, and medical sectors. In addition, Niobium has no effective substitutes.

    Niobium Properties. Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d 4 5s niobium atom has a radius of pm and its Van der Waals radius is its elemental form, CAS , niobium has a gray metallic appearance. Niobium crystal bar. From the source:This is a sample of niobium crystal bar, produced by the same basic method as the Van Arkel/de Boer (Iodide) crystal bar process used to purify hafnium, zirconium, titanium, and occasionally thorium, though with different chemical precursors and reaction conditions in order to adapt the process to niobium.

It is most commonly used in the creation of numerous metal alloys. Small amounts of niobium (as little as %) can significantly improve a metal’s performance characteristics.

Niobium is playing a key role in advanced materials that are driving innovation, performance, safety Niobium data manual book efficiencies in the Mobility sector. Structural Niobium helps solve complex engineering challenges Niobium data manual book effectively and makes modern projects more efficient.

Applications for niobium. Niobium consumption is dominated by its use as additive to high strength low alloy steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool steels, ships hulls, railroad tracks.

However, there are a number of other applications for niobium metal and its compounds. Tantalum and niobium in arc magmas are depleted relative to REEs, so that Nb/La and Ta/La are lower than in the primitive mantle and in MORBs.

Depletion of primitive arc magmas in tantalum and niobium relative to lanthanum and thorium (Figure 14) is ubiquitous (a few niobium-enriched lavas—e.g., Kepezhinskas et al., —form a distinct anomaly, which will not be discussed in this chapter). The world is changing fast and the way people move is changing, too.

Niobium is playing a key role in advanced materials that are driving innovation, performance, safety and efficiencies in the Mobility sector. The knowledge of thermophysical properties of materials is essential for designing nuclear power plants (NPP).

The results of the research work on thermophysical properties of materials for the first fifteen years of nuclear power engineering development in the Soviet Union (–65) are reviewed in a reference book [1]. Niobium is chemically very similar to Ta. It has a lower melting temperature and at g/cm 3, Nb has the lowest density of all the refractory metals and is thus a leading candidate for applications where high-temperature strength to weight ratio is the most critical requirement.

Niobium metal is soft, ductile and easy to machine, but suffers from very poor oxidation resistance. The story of niobium's discovery is a bit confusing.

The first governor of Connecticut, John Winthrop the Younger, discovered a new mineral around He named the mineral columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6) and sent a sample of it to the British Museum in London, England. If the substance is covered by more than one CLH entry (e.g.

disodium tetraborate EC no. ––4, is covered by three harmonisations: ––00–4; ––01–1 and ––02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or. A.V. Mokhov, T.A. Gornostaeva, P.M. Kartashov, O.A.

Based on incomplete world estimates published by the United States Geological Survey (USGS) forthe largest holders of the world's niobium resources are Brazil with kt and Canada with kt. 6 USGS data also estimates that world production of niobium in was kt, which represents an increase of 9% on production of Niobium occurs naturally most frequently in the form of columbite ore, which is also known as niobite and has the chemical formula (Fe,Mn) [(Nb,Ta)O3]2.

Niobium-titanium is a superconducting at temperatures below ten Kelvin and is used in a number of large superconducting magnets such as the Tevatron accelerator at Fermilab and most recently the Large Hadron Collider, where the niobium-containing magnets are cooled to Kelvin and operate at magnetic fields of up to Tesla.

Roskill has released its new niobium market report with forecasts out to It is essential reading for anyone requiring a comprehensive overview of this sector. Niobium: Global Industry, Markets & Outlook to13 th Edition is now available from Roskill Information Services.

Compare to data provided in literature, speed must be increased by a large factor when dealing with high RRR material. Fermilab experience with machining niobium on a lathe has determined that the primary points to emphasize are: (1) Always keep tools sharp, (2) Use manual feed (rate at operator’s discretion) to peel niobium chips away.The following is a list of techniques that can be used when working with niobium, special considerations for the metal, and tips for achieving the best results: Drilling.

Standard high-speed steel drills can be used with good results. The peripheral lands of the drill should be checked often for excessive wear to prevent drilling undersized holes.Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given inand niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.
