CAS 7440-58-6
:Hafnium
Beschreibung:
Hafnium ist ein Übergangsmetall mit dem chemischen Symbol Hf und der CAS-Nummer 7440-58-6. Es zeichnet sich durch seinen hohen Schmelzpunkt aus, der einer der höchsten unter allen Elementen ist, was es in Hochtemperaturanwendungen nützlich macht. Hafnium hat ein silbergraues Aussehen und zeigt einen metallischen Glanz. Es ist bekannt für seine hervorragende Korrosionsbeständigkeit, insbesondere in sauren Umgebungen, aufgrund der Bildung einer schützenden Oxidschicht. Hafnium hat eine relativ hohe Dichte und wird häufig in Kernreaktoren eingesetzt, da es eine starke Fähigkeit zur Neutronenabsorption hat. Darüber hinaus wird es in der Herstellung von Hochleistungslegierungen und in der Halbleiterindustrie aufgrund seiner Eigenschaften als dielektrisches Material verwendet. Hafnium kommt typischerweise in Zirkoniummineralien vor und wird durch Prozesse wie fraktionierte Kristallisation extrahiert. Sein chemisches Verhalten ähnelt dem von Zirkonium, und es bildet verschiedene Verbindungen, einschließlich Hafnium-Oxid, das in der Elektronik und Optik von Bedeutung ist. Insgesamt machen die einzigartigen Eigenschaften von Hafnium es wertvoll für verschiedene fortschrittliche technologische Anwendungen.
