Gadolinium

Beschreibung:

Gadolinium ist ein silberweißes, verformbares und duktiles Seltenmetall, das unter der Lanthanoid-Serie im Periodensystem klassifiziert ist. Es hat die Ordnungszahl 64 und ist bekannt für seine einzigartigen magnetischen Eigenschaften, insbesondere seine Fähigkeit, bei Raumtemperatur ferromagnetisch zu werden, was unter den Lanthanoiden relativ selten ist. Gadolinium ist hochreaktiv, insbesondere in pulverförmiger Form, und kann schnell oxidieren, wenn es Luft ausgesetzt wird, wodurch eine schützende Oxidschicht entsteht. Es hat einen hohen Schmelzpunkt und wird häufig in verschiedenen Anwendungen eingesetzt, einschließlich in der Magnetresonanztomographie (MRT) als Kontrastmittel aufgrund seiner paramagnetischen Eigenschaften. Darüber hinaus werden Gadolinium-Verbindungen in Neutronenfanganwendungen und als Phosphore in bestimmten Arten von Bildschirmen verwendet. Das Metall wird typischerweise aus Mineralien wie Bastnäsit und Monazit gewonnen und wird oft durch komplexe Extraktionsmethoden verarbeitet. Sicherheitsvorkehrungen sind erforderlich, wenn Gadolinium und seine Verbindungen gehandhabt werden, da sie in bestimmten Formen und Konzentrationen toxisch sein können.
