Niobium–tin is an intermetallic compound of niobium (Nb) and tin (Sn), used industrially as a type II superconductor. This intermetallic compound has a simple structure: A3B. It is more expensive than niobium-titanium (NbTi), but remains superconducting up to a magnetic flux density of 30 teslas [T] (300,000 G), compared to a limit of roughly 15 T for NbTi. Nb3Sn was discovered to be a superconductor in 1954. The material's ability to support high currents and magnetic fields was discovered in 1961 and started the era of large-scale applications of superconductivity.

  • Niobium–tin is an intermetallic compound of niobium (Nb) and tin (Sn), used industrially as a type II superconductor. This intermetallic compound has a simple structure: A3B. It is more expensive than niobium-titanium (NbTi), but remains superconducting up to a magnetic flux density of 30 teslas [T] (300,000 G), compared to a limit of roughly 15 T for NbTi. Nb3Sn was discovered to be a superconductor in 1954. The material's ability to support high currents and magnetic fields was discovered in 1961 and started the era of large-scale applications of superconductivity. The critical temperature is 18.3 kelvins (−254.8 °C; −426.7 °F). Application temperatures are commonly around 4.2 K (−268.95 °C; −452.11 °F), the boiling point of liquid helium at atmospheric pressure. In April 2008 a record non-copper current density was claimed of 2,643 A mm−2 at 12 T and 4.2 K.
  • Le niobium-étain, aussi appelé triniobium-étain, est un composé chimique métallique polycristallin constitué de niobium (Nb) et d'étain (Sn) de formule brute Nb3Sn. Ce composé intermétallique fait partie de la famille cristallographique (en)et est utilisé dans l'industrie comme supraconducteur de type II. Cette structure se présente souvent avec la stœchiométrie A3B et appartient au groupe d'espace Pm-3m. Les positions des atomes de la structure sont les suivantes: * 2 atomes B en position: (0,0,0) et (1/2,1/2,1/2) * 6 atomes A en position: (1/4,0,1/2) ; (1/2,1/4,0) ; (0,1/2,1/4) ; (3/4,0,1/2) ; (1/2,3/4,0) ; (0,1/2,3/4) Nb3Sn est supraconducteur sous une température critique de l'ordre de 18 Kelvins [K] (−255 °C) à 0 Teslas [T] et peut résister à des champs magnétiques allant jusqu'à 30 T. Cependant, le niobium-étain est onéreux, fragile et difficile à produire, c'est pourquoi on préfère parfois choisir leniobium-titane(NbTi), qui est supraconducteur sous une température critique de l'ordre de 9 K (−264 °C) et résiste à des champs magnétiques jusqu'à 15 T. Néanmoins, on observe une augmentation de la production de niobium-étain ces vingt dernières années, car il peut supporter de plus grandes densités de courant que le niobium-titane et donc permettre de développer ou améliorer des applications à grande échelle comme l'amélioration du LHC grâce au développement d'aimants supraconducteurs capables de générer plus de 10 T.
