• Hafnium — Wikipédia

    UtilisationPropriétésDécouverteToxicitéMécanismeLe hafnium ressemble chimiquement au zirconium et on le trouve dans tous les minerais de zirconium. Le corps simple hafnium est un métal de transition tétravalent d'un aspect gris argenté. On l'utilise dans les alliages de tungstène pour la confection de filaments et d'électrodes, et comme absorbeur de neutrons dans les barres (ou croix) de contrôle de la réactivité nucléaire. L'abondance du hafnium dans la croûte terrestre est de 5,8 ppm在fr.wikipedia上查看更多信息Groupe: 4
