- Specialized
- The cavity consists of two spherical, superconducting niobium mirrors surrounded by a cylindrical ring.
- niobium concentration
- niobium-titanium
- vanadium and niobium
Examples
-

Etymology
Niobium comes from Niobe, a woman in Greek myth who was the daughter of Tantalus. Scientists gave the metal this name because it is very like tantalum, so the two are like family and hard to tell apart, which helps explain why niobium often appears in strong alloys and in superconducting magnets.
