CAS 7440-25-7: Tantal

Beschreibung: Tantal ist ein seltener, harter, blau-grauer Metall, das hochgradig korrosionsbeständig ist und einen hohen Schmelzpunkt hat, was es in verschiedenen industriellen Anwendungen wertvoll macht. Es gehört zur Gruppe 5 des Periodensystems und wird als Übergangsmetall klassifiziert. Tantal ist bekannt für seine hervorragende Leitfähigkeit und wird häufig in der Produktion von Kondensatoren und Hochleistungswiderständen verwendet, insbesondere in der Elektronikindustrie. Seine Widerstandsfähigkeit gegen chemische Angriffe ermöglicht es, in Umgebungen eingesetzt zu werden, die andere Metalle korrodieren würden, wie in chemischen Verarbeitungsanlagen und chirurgischen Implantaten. Tantal ist auch biokompatibel, was es für medizinische Anwendungen geeignet macht. Das Metall wird typischerweise aus Tantal-haltigen Mineralien wie Columbit und Tantalit durch komplexe Trennprozesse gewonnen. Aufgrund seiner Knappheit und der geopolitischen Probleme, die mit seinem Abbau verbunden sind, wird Tantal als kritisches Material in den Bereichen Technologie und Verteidigung angesehen. Insgesamt machen die einzigartigen Eigenschaften von Tantal es zu einem wesentlichen Element in der modernen Technologie und Materialwissenschaft.
