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.

CAS :Produit contrôlé<p>Bismuth is a metal that has been used in the treatment of infectious diseases. It is an element with atomic number 83, symbol Bi, and atomic weight 208.904. Bismuth is unique in that it has the highest naturally occurring radioactivity of any element. This property makes bismuth useful for certain medical purposes, such as treating infectious diseases and cancer. Bismuth's coordination geometry can be described as octahedral with a low-dose group consisting of six water molecules and two ligands comprising either citrate or oxalate ions. The ligands bind to bismuth by means of a strong S-S bond in a 2:1 ratio and are coordinated to the metal through oxygen atoms. The redox potential for bismuth is -0.792 V versus standard hydrogen electrode (SHE). It was reported that the reaction mechanism for bismuth is similar to that of other metals, involving oxidation from +3 to +5</p>Formule :BiDegré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :208.98 g/mol
