General information about niobium

Pure niobium is a silver colored metal that is very resistant to corrosion. The primary source of this element is the mineral columbite. This mineral also contains tantalum, so they are found in approximately equal proportions in the ore. Columbite is found in Canada, Brazil, Australia, Nigeria, and elsewhere. Some niobium is also obtained as a byproduct of tin extraction. Evek GmbH offers to buy niobium at producer prices. The price from the manufacturer. The supplier guarantees product delivery to any location specified by the customer.

This metal is used as an additive to a variety of alloys, including stainless steel to increase the strength over a wide temperature range. Alloys alloyed with niobium are particularly widespread in the aviation and aerospace industries. They are used in jet engines and rocket fairings, building beams for high-rise buildings and oil rigs. Such alloys are widely used in oil and gas pipelines. Niobium has superconducting properties. It is used in superconducting magnets for particle gas pedals, MRI scanners and NMR equipment. NbO oxide compounds are added to glass to increase the refractive index, which makes it possible to produce corrective glasses with thinner lenses.

Nb, technical characteristic.

1. The metal is coated with an oxide layer in air, the hue of which (blue, green or yellow) depends on the thickness.
2. The basis of corrosion resistance is a tough oxide film.
3. The metal begins to oxidize rapidly in air at 200°.
4. The chemical properties of niobium are very similar to those of tantalum.

Niobium is one of the five major refractory metals (metals with very high resistance to heat and wear). The other refractory metals are tungsten, molybdenum, tantalum, and rhenium.
