High Purity 99.95% Niobium and Niobium Alloy Sputtering Targets
What is Niobium?
- Niobium is a chemical element with atomic number 41 and is represented with the symbol Nb in the Periodic Table.
- It is a soft, ductile transition metal which is resistant to corrosion due to the presence of an oxide layer on its surface.
- It is one of the most common elements found in the Earth’s Crust. It is often found in the pyrochlore mineral.
Uses of Niobium
- It is used in stainless steel alloys for cutting tools, nuclear reactors, jets, missiles, and welding rods.
- It is used in the manufacturing of MRI scanners and NMR equipment.
- Its alloys are used in making surgical implants.
- It is used for the production of stainless steel and high-temperature resistant alloys.
Properties of Niobium
- At cryogenic temperatures, Niobium becomes a superconductor.
- Niobium and its compounds are toxic to some extent.
- When exposed to air at room temperature, metal takes on a bluish tinge for extended periods.
- Niobium comprises one stable isotope in the Earth’s crust.
