- 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
