Niobium was discovered in 1801 by the English chemist Charles Hatchett in a mineral from North America. It was originally named columbium, but the name niobium was later internationally adopted, inspired by Niobe from Greek mythology.
Niobium is mainly obtained from the minerals pyrochlore and columbite. Brazil is the world's largest producer, supplying most of the global demand.

Niobium is used in high-strength steels, superconducting magnets, MRI scanners, particle accelerators, jet engines, rockets and advanced pipelines.
Titanium, Zirconium, Tantalum and Iron
Niobium is highly resistant to corrosion, but at elevated temperatures it reacts with oxygen and certain halogens if left unprotected.

Even tiny amounts of niobium dramatically increase the strength, toughness and durability of steel while keeping it lightweight.
Less than 0.1% niobium added to steel can significantly improve its strength, allowing engineers to build lighter yet stronger structures.
Niobium-strengthened steel is used in skyscrapers, long-span bridges, oil pipelines and high-speed railways because it combines strength with reduced weight.
Niobium-titanium and niobium-tin alloys become superconductors at very low temperatures. They are essential for MRI scanners, particle accelerators and fusion research.
The powerful superconducting magnets inside MRI machines often rely on niobium-based alloys to generate stable magnetic fields for detailed medical imaging.
Niobium alloys withstand extreme temperatures and are used in rocket engines, spacecraft components and advanced jet propulsion systems.
Niobium teaches an important lesson in engineering: sometimes, a tiny addition can make an enormous difference. A very small amount added to steel transforms it into a material capable of supporting skyscrapers, transporting energy across continents and enabling some of humanity's most advanced scientific discoveries.
Scientists are studying niobium for quantum computing, superconducting electronics, clean-energy technologies and future fusion reactors.
Niobium was forged inside ancient stars through stellar nucleosynthesis. Today it forms part of Earth's crust and contributes to technologies that explore the universe.
The Large Hadron Collider at CERN uses thousands of superconducting magnets made with niobium alloys to steer particles traveling close to the speed of light.
