CAS 7440-69-9
:Bismuto
Descrizione:
Bismuto, con il simbolo chimico Bi e numero CAS 7440-69-9, è un metallo post-transizione noto per le sue proprietà uniche. Ha una densità relativamente bassa e una massa atomica elevata, rendendolo uno degli elementi stabili più pesanti. Bismuto è caratterizzato dalla sua natura fragile e da un aspetto lucido e bianco argentato con una leggera sfumatura rosa. Mostra una bassa conducibilità termica ed è un cattivo conduttore di elettricità rispetto ad altri metalli. Bismuto ha un alto punto di fusione e si espande durante la solidificazione, il che è insolito per i metalli. Chimicamente, è relativamente inerte, mostrando resistenza all'ossidazione e alla corrosione, e non reagisce con acqua o acidi diluiti. I composti di Bismuto, come il subsalicilato di Bismuto, sono utilizzati in medicina, in particolare per problemi gastrointestinali. Inoltre, Bismuto è non tossico rispetto ad altri metalli pesanti, rendendolo un'alternativa più sicura in varie applicazioni, tra cui cosmetici e prodotti farmaceutici. Le sue proprietà uniche e la bassa tossicità hanno portato a un crescente interesse per il suo utilizzo in varie applicazioni industriali e mediche.
