Tellur

Beschreibung:

Tellur ist ein chemisches Element mit dem Symbol Te und der Ordnungszahl 52. Es ist ein Halbmetall, das sowohl Eigenschaften von Metallen als auch von Nichtmetallen aufweist. Tellur hat typischerweise ein silber-weißes Aussehen und eine spröde Textur, was es weniger verformbar macht als Metalle. Es hat einen relativ hohen Schmelzpunkt und Siedepunkt im Vergleich zu vielen anderen Elementen. Tellur kommt in der Natur hauptsächlich in Form von Telluridmineralien vor und wird oft als Nebenprodukt der Kupferraffination gewonnen. Es ist bekannt für seine Halbleitereigenschaften, was es in verschiedenen elektronischen Anwendungen, einschließlich Solarzellen und thermoelektrischen Geräten, wertvoll macht. Darüber hinaus können Tellur-Verbindungen ein interessantes chemisches Verhalten zeigen, wie die Bildung stabiler Oxide und Sulfide. Während Tellur in kleinen Mengen für bestimmte biologische Prozesse essentiell ist, kann es in größeren Mengen toxisch sein. Seine einzigartigen Eigenschaften und Anwendungen machen es zu einem wichtigen Element in der Materialwissenschaft und Technologie.
