  • Niobium, or columbium is a chemical element that has the symbol Nb.
  • Niobium is a metal that is gray in appearance and ideal for use with steel to create an alloy that can be used in a number of products.
  • Niobium is a shiny grey, ductile metal that takes on a bluish tinge when exposed to air at room temperature for extended periods.
  • Columbium (symbol Cb) was the name originally given to this element, but the International Union of Pure and Applied Chemistry (IUPAC) officially adopted "niobium" as the name for element.
  • Niobium occurs primarily in two minerals, columbite and pyrochlore. Niobium always occurs with tantalum in these minerals.
  • Only one naturally occurring isotope of niobium exists, niobium-93.
  • The first step in preparing niobium metal is to separate its compounds from tantalum in an ore.
  • Niobium becomes a superconductor when lowered to cryogenic temperatures.
    Electropolishing (EP) has been proven a necessary surface processing method for high-gradient superconducting niobium cavities.
  • A techniques has been developed for processing niobium via powder metallurgy and some have applied powder injection molding to niobium-based alloys and superalloys.
  • Conversion of niobium oxide units into HSLA ferro-niobium through the aluminothermic reduction process or by reduction in an electric arc furnace.
  • Niobium cooled by superfluid Helium contained in stainless steel cryostats.
  • The annealing behavior of niobium single crystal deformed by 8 Equal channel angular extrusion(ECAE) passes.
  • Niobium has begun to attract attention as a metal that can be used in the creation of jewelry.
  • Niobium is used in many alloys. An alloy is made by melting and mixing two or more metals.
  • Niobium is used in special steel alloys as well as in welding, nuclear industries, electronics and optics.
  • Niobium Oxide capacitors are gaining a presence in the electronics marketplace as a non-burning solution, practical for many applications.
  • High strength oil country tubular goods(OCTG) used in sour and gas well applications are generally microalloyed with niobium to improve both the strength and the resistance to sulphide stress cracking (SSC).
  • Niobium and tantalum anodic oxides of optimal thickness have enabled the manufacture of a new generation of bioengineering products displaying minimal corrosion.
  • The basic consideration when applying niobium to steels, is that it forms very stable carbides to facilitate grain refinement and precipitation hardening as strengthening mechanisms in structural steels.
  • Columbium, in the form of ferrocolumbium, is used worldwide mostly as an alloying element in steels and in superalloys.
  • The columbium price is driven by the availability of columbium mineral feed materials, recycling being an insignificant source of supply.
  • Brazil and Canada are the major producers of columbium mineral concentrates and converters of the material to ferrocolumbium.
  • Brazil’s production of columbium concentrates, mostly pyrochlore, accounts for more than 85% of total world production of columbium.
  • CBMM accounted for 87.66% of the total of foreign exchange in dollars-FOB generated by exports of products made from niobium (Nb2O5) in the country.
  • Niobium demand has increased due to a general increase in the use of niobium, high demand in China and the additional use of niobium as a substitute for other, higher-priced specialty alloys.
  • Niobium is also used in the manufacture of jet engine components, rocket subassemblies and combustion equipment
    containing cobalt, iron and nickel-based alloys where strength at high temperature is crucial
  • When treated with sodium hydroxide Niobium is a preferred metal for use in medical implants due to its ability to aid Osseo integration – the process
    whereby bone tissue adheres to metal. Niobium also is physiologically inert and thus can be used in devices such as pacemakers.
  • China is the largest consumer of niobium and Brazil is the largest producer
