CAS 7440-47-3

Chrome

Description :

Chrome, avec le numéro CAS 7440-47-3, est un métal de transition connu pour sa haute résistance à la corrosion et sa dureté. Il a un numéro atomique de 24 et est représenté par le symbole Cr dans le tableau périodique. Chrome présente une brillance métallique gris argenté et se trouve principalement dans la nature sous forme de minerai de chromite. Il est caractérisé par sa capacité à former divers états d'oxydation, avec +3 et +6 étant les plus courants dans les composés. Chrome est largement utilisé dans la production d'acier inoxydable et d'autres alliages, améliorant leur résistance et leur résistance à l'oxydation. De plus, il joue un rôle crucial dans la fabrication de pigments, comme l'oxyde de Chrome, qui confère des couleurs vives aux céramiques et aux peintures. En termes de réactivité chimique, Chrome peut réagir avec l'oxygène et d'autres non-métaux, formant des oxydes et d'autres composés. Bien qu'il soit essentiel en quantités traces pour les fonctions biologiques, certains composés de Chrome, en particulier le Chrome hexavalent, sont connus pour être toxiques et cancérigènes, nécessitant une manipulation et une réglementation prudentes.
