CAS 7440-58-6
:Hafnium
Description :
Hafnium est un métal de transition avec le symbole chimique Hf et le numéro CAS 7440-58-6. Il se caractérise par son point de fusion élevé, qui est l'un des plus élevés parmi tous les éléments, ce qui le rend utile dans les applications à haute température. Hafnium a une apparence gris argenté et présente un éclat métallique. Il est connu pour sa excellente résistance à la corrosion, en particulier dans les environnements acides, en raison de la formation d'une couche d'oxyde protectrice. Hafnium a une densité relativement élevée et est souvent utilisé dans les réacteurs nucléaires, car il a une forte capacité à absorber les neutrons. De plus, il est utilisé dans la production d'alliages haute performance et dans l'industrie des semi-conducteurs pour ses propriétés en tant que matériau diélectrique. Hafnium se trouve généralement dans les minéraux de zirconium et est extrait par des procédés tels que la cristallisation fractionnée. Son comportement chimique est similaire à celui du zirconium, et il forme divers composés, y compris l'oxyde de Hafnium, qui est significatif en électronique et en optique. Dans l'ensemble, les propriétés uniques de Hafnium le rendent précieux dans diverses applications technologiques avancées.
