CAS 7440-03-1: Niobium
Description :
Niobium, avec le symbole chimique Nb et le numéro CAS 7440-03-1, est un métal de transition connu pour son point de fusion élevé et son excellente résistance à la corrosion. C'est un métal gris argenté qui est ductile et peut être facilement façonné. Niobium est principalement utilisé dans la production d'alliages d'acier à haute résistance, qui améliorent la résistance et la ténacité des matériaux utilisés dans la construction et la fabrication. Il a une structure cristalline cubique centrée sur le corps et présente des propriétés supraconductrices à basse température, ce qui le rend précieux dans des applications telles que les machines d'IRM et les accélérateurs de particules. Niobium est également résistant à l'oxydation et peut former une couche d'oxyde protectrice, ce qui contribue à sa durabilité dans divers environnements. De plus, il est relativement rare dans la croûte terrestre et est principalement obtenu à partir de minéraux tels que la columbite et le pyrochlore. En raison de ses propriétés uniques, Niobium joue un rôle significatif dans la technologie moderne et la science des matériaux.

CAS :Niobium sputtering target is used in high temperature engineering products. It is also used as an alloying agent for certain steels where it greatly improves the strength of the resulting material. It is also finds applications in atomic reactors due to its corrosion resistance and, when combined with either tin (Nb3Sn) or zirconium, it has a high degree of superconductivity.
