Niobium is a metal with a wide range of uses, including:

Niobium Metal Part

Alloys: Niobium is used in alloys to improve strength, especially at low temperatures. Alloys containing niobium are used in jet engines, rockets, oil and gas pipelines, etc.
Superconducting materials: Niobium is used in superconducting magnets in MRI scanners.
Medical implants: Niobium’s biocompatibility and corrosion resistance make it suitable for medical implants and radiation shielding.
Energy storage: Niobium has been used in new applications, including energy storage.
Optical glass: Niobium oxide is used in lanthanum borate glass, which is used to make corrective glasses with thinner lenses.
Clay-based refractories: Niobium is used in clay-based refractories such as mortars, mixes, and lightweight insulation.
Jewelry: Niobium is used in hypoallergenic jewelry.
Nuclear reactor control rods: Niobium is used in nuclear reactor control rods.
Crucibles for making synthetic diamonds: Niobium is used in crucibles for making synthetic diamonds.

Main chemical properties of niobium:

Niobium crucible

Oxidation state: mainly +5
Surface oxide layer: Niobium forms a thin protective oxide layer on its surface, which prevents it from most reactions with air and water.
Acid resistance: Resistant to most acids, but soluble in hydrofluoric acid
Halogen reactivity: Resists most acids, but soluble in hydrofluoric acid
Halogen reactivity: Resists halogens when heated to form niobium (V) halides
Similar to tantalum: Due to the similar electronic structure, the chemical properties of niobium are very similar to tantalum
Superconducting properties: Niobium exhibits superconducting properties at low temperatures

Niobium is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal. It has physical and chemical properties similar to the element tantalum, and the two are therefore difficult to distinguish.

Nb is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. Other applications of Nb include welding, nuclear industries, electronics, optics, numismatics, and jewelry. In the last two applications, the low toxicity and iridescence produced by anodization are highly desired properties.

We provide Nb metal, Nb alloys, superconducting materials, Nb compounds, etc.
