CAS 7440-21-3
:Silicium
Description :
Silicium, avec le numéro CAS 7440-21-3, est un élément métalloïde qui joue un rôle crucial dans diverses industries, en particulier dans l'électronique et la science des matériaux. Il se caractérise par son éclat métallique et sa nature fragile sous forme cristalline. Silicium a un point de fusion élevé et est un mauvais conducteur d'électricité à température ambiante, mais sa conductivité augmente considérablement lorsqu'il est dopé avec des impuretés, ce qui en fait un matériau semi-conducteur fondamental. Il est abondant dans la croûte terrestre, principalement trouvé sous forme de silicates et de dioxyde de Silicium. Silicium est essentiel dans la production de verre, de céramique et de béton, et il est un composant clé dans la fabrication de cellules solaires et de puces informatiques. De plus, Silicium présente une capacité de liaison tétravalente, lui permettant de former des liaisons covalentes stables avec d'autres éléments, ce qui est vital pour créer divers composés à base de Silicium. Sa polyvalence et ses propriétés uniques font de Silicium une pierre angulaire de la technologie moderne et de l'ingénierie des matériaux.
