Wolfram

Beschreibung:
Wolfram, mit der CAS-Nummer 7440-33-7, ist ein Übergangsmetall, das für seine bemerkenswerten Eigenschaften bekannt ist. Es hat den höchsten Schmelzpunkt aller Elemente, was es in Hochtemperaturanwendungen außergewöhnlich wertvoll macht. Wolfram zeichnet sich durch seine dichte, harte und spröde Natur mit metallischem Glanz aus. Es zeigt eine hervorragende Leitfähigkeit sowohl für Wärme als auch für Elektrizität, was es für verschiedene elektrische Anwendungen geeignet macht. Chemisch ist Wolfram relativ inert und widersteht Korrosion und Oxidation bei Raumtemperatur, obwohl es bei erhöhten Temperaturen mit Halogenen und Säuren reagieren kann. Seine Verbindungen, wie z.B. Wolfram-Karbid, werden aufgrund ihrer Härte häufig in Schneidwerkzeugen und Schleifmitteln eingesetzt. Wolfram wird auch in der Produktion von Filamenten für Glühbirnen und in der Luft- und Raumfahrt sowie der Militärindustrie aufgrund seiner Festigkeit und Haltbarkeit verwendet. Darüber hinaus spielt Wolfram eine bedeutende Rolle in der Produktion von Legierungen, die die Eigenschaften von Materialien in anspruchsvollen Umgebungen verbessern. Insgesamt macht die einzigartige Kombination von physikalischen und chemischen Eigenschaften von Wolfram es zu einem unverzichtbaren Material in verschiedenen industriellen Anwendungen.
