Definitions and examples


The chemical element of atomic number 41, a silver-grey metal of the transition series, used in superconducting alloys.
  1. 'Previous attempts to lower the switching temperature have incorporated low levels of elements such as tungsten, molybdenum, niobium and fluorine.'
  2. 'The mine in question will be digging for niobium, a rare metal used as a steel alloy to save on weight and thickness, which is more resistant to corrosion and is easier to weld.'
  3. 'Likewise, we could explain the known properties of Earth's core by an alloy of niobium but choose not to do so because a much more abundant element - iron - can do the job.'
  4. 'Sodium is also used as a chemical reducing agent in producing titanium, zirconium, niobium, and tantalum from their fused salts.'
  5. 'Depending on specific requirements related to their use, hard metals might additionally contain small quantities of chromium, niobium, molybdenum, titanium, tantalum or vanadium carbides.'
  6. 'The proposed mine, which would dig for niobium, a rare metal, would be carved out of land near the Kahnesatake Mohawk reserve and the village of Oka.'
  7. 'Other elements added to improve characteristics include nickel, molybdenum, copper, titanium, aluminum, silicon, niobium, nitrogen, sulfur, and selenium.'
  8. 'The materials all include oxygen, and one, for example, also contains niobium, tantalum, and zirconium.'
  9. 'This resource is potentially globally significant as a source of niobium and tantalum.'
  10. 'A previous study of the columbite-tantalite series minerals indicated a similar change for tin, tantalum, niobium, and manganese.'
