CAS 7440-69-9
:Wismut
Beschreibung:
Wismut, mit dem chemischen Symbol Bi und der CAS-Nummer 7440-69-9, ist ein Post-Übergangsmetall, das für seine einzigartigen Eigenschaften bekannt ist. Es hat eine relativ niedrige Dichte und eine hohe Atommasse, was es zu einem der schwersten stabilen Elemente macht. Wismut zeichnet sich durch seine spröde Natur und sein glänzendes, silber-weißes Aussehen mit einem leichten rosafarbenen Schimmer aus. Es zeigt eine niedrige Wärmeleitfähigkeit und ist im Vergleich zu anderen Metallen ein schlechter Leiter von Elektrizität. Wismut hat einen hohen Schmelzpunkt und dehnt sich beim Erstarren aus, was für Metalle ungewöhnlich ist. Chemisch ist es relativ inert, zeigt Widerstand gegen Oxidation und Korrosion und reagiert nicht mit Wasser oder verdünnten Säuren. Wismut-Verbindungen, wie Wismut-Subsalicylat, werden in der Medizin verwendet, insbesondere bei gastrointestinalen Problemen. Darüber hinaus ist Wismut im Vergleich zu anderen Schwermetallen ungiftig, was es zu einer sichereren Alternative in verschiedenen Anwendungen, einschließlich Kosmetika und Pharmazeutika, macht. Seine einzigartigen Eigenschaften und die geringe Toxizität haben zu einem gestiegenen Interesse an seiner Verwendung in verschiedenen industriellen und medizinischen Anwendungen geführt.
