CAS 7440-69-9
:Bismuth
Description :
Bismuth, avec le symbole chimique Bi et le numéro CAS 7440-69-9, est un métal post-transition connu pour ses propriétés uniques. Il a une densité relativement faible et une masse atomique élevée, ce qui en fait l'un des éléments stables les plus lourds. Bismuth se caractérise par sa nature cassante et son apparence brillante et argentée avec une légère teinte rose. Il présente une faible conductivité thermique et est un mauvais conducteur d'électricité par rapport à d'autres métaux. Bismuth a un point de fusion élevé et se dilate lors de la solidification, ce qui est inhabituel pour les métaux. Chimiquement, il est relativement inerte, montrant une résistance à l'oxydation et à la corrosion, et ne réagit pas avec l'eau ou les acides dilués. Les composés de Bismuth, comme le subsalicylate de Bismuth, sont utilisés en médecine, en particulier pour les problèmes gastro-intestinaux. De plus, Bismuth est non toxique par rapport à d'autres métaux lourds, ce qui en fait une alternative plus sûre dans diverses applications, y compris les cosmétiques et les produits pharmaceutiques. Ses propriétés uniques et sa faible toxicité ont conduit à un intérêt croissant pour son utilisation dans diverses applications industrielles et médicales.
