Niob

Beschreibung:
Niob, mit dem chemischen Symbol Nb und der CAS-Nummer 7440-03-1, ist ein Übergangsmetall, das für seinen hohen Schmelzpunkt und seine hervorragende Korrosionsbeständigkeit bekannt ist. Es ist ein silbergraues Metall, das duktil ist und leicht geformt werden kann. Niob wird hauptsächlich in der Herstellung von hochfesten Stahllegierungen verwendet, die die Festigkeit und Zähigkeit der in Bau und Fertigung verwendeten Materialien verbessern. Es hat eine raumzentrierte kubische Kristallstruktur und zeigt bei niedrigen Temperaturen supraleitende Eigenschaften, was es in Anwendungen wie MRT-Geräten und Teilchenbeschleunigern wertvoll macht. Niob ist auch oxidationsbeständig und kann eine schützende Oxidschicht bilden, die zu seiner Haltbarkeit in verschiedenen Umgebungen beiträgt. Darüber hinaus ist es relativ selten in der Erdkruste und wird hauptsächlich aus Mineralien wie Columbit und Pyrochlor gewonnen. Aufgrund seiner einzigartigen Eigenschaften spielt Niob eine bedeutende Rolle in der modernen Technologie und Materialwissenschaft.
