CAS 7440-45-1

Cérium

Description :

Cérium est un métal ductile de couleur argentée qui appartient à la série des lanthanides du tableau périodique, avec le numéro atomique 58 et le numéro CAS 7440-45-1. Il est connu pour son point de fusion relativement élevé et est l'un des éléments de terres rares les plus abondants. Cérium présente une variété d'états d'oxydation, les plus courants étant +3 et +4, qui contribuent à son comportement chimique diversifié. Il s'oxyde facilement dans l'air, formant une couche d'oxyde protectrice, et peut réagir avec l'eau à des températures élevées. Les composés de Cérium, tels que l'oxyde de Cérium, sont largement utilisés comme catalyseurs dans les convertisseurs catalytiques automobiles et dans diverses applications industrielles, y compris le polissage du verre et comme composant dans les phosphores pour l'éclairage. De plus, Cérium a des applications en métallurgie et comme additif dans certains alliages pour améliorer leurs propriétés. Ses caractéristiques uniques font de Cérium un élément important tant dans les contextes industriels que technologiques.

Cerium

CAS : 7440-45-1

Cerium is a rare earth metal and has been studied for its minimal toxicity. Cerium has been shown to be biocompatible and can be used in the treatment of inflammatory diseases. Cerium oxide nanoparticles have been shown to have minimal toxicity and are being studied as a possible drug delivery system for the treatment of osteoarthritis. Cerium has also been shown to have antioxidant activity, which may be due to its ability to scavenge reactive oxygen species or chelate iron. Cerium oxide nanoparticles have also been shown to have potential application in wastewater treatment, as they are able to adsorb organic matter, heavy metals, and radioactive elements.
