What is Niobium ?

Niobium, also known as columbium, is a chemical element with the symbol Nb and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the earth’s atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel.

Niobium is a rare, soft, malleable, ductile, gray-white metal. Niobium exhibits similar but slightly lower resistance against chemicals corrosive to tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, the halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents. However, 90% of its total demand arises from the production of high-strength low-alloy steels, whereas rolled niobium–based products account for 4% and superalloys and compounds (oxides and chemicals) account for 3% each.

Application of Niobium

Used for the heat exchange tube.
The protect tube of thermometer in petrochemical industry.
The electronics industry.
Niobium is used for the production of high-temperature-resistant alloys and special stainless steels.
Small amounts of niobium impart greater strength to other metals, especially those that are exposed to low temperatures.
Niobium carbide is used in cutting tools.
It is used in stainless steel alloys for nuclear reactors, jets, missiles, cutting tools, pipelines, super magnets and welding rods.
Niobium-tin and niobium-titanium alloys are used as wires for superconducting magnets capable of producing exceedingly strong magnetic fields.
Niobium is also used its pure form to make superconducting accelerating structures for particle accelerators.
Niobium alloys are used in surgical implants because they do not react with human tissue.

Why Use Niobium ?

Niobium is a useful metal in a range of specialist alloys. In amounts as low as 0.1 per cent it has a significant strengthening effect on steel, making it suitable for use in gas pipelines for example. It is also involved in some highly temperature-stable superalloys used for engine parts in the aerospace industry.
