:Yttrium
Beschreibung:
Yttrium ist ein silbermetallisches Element mit der Ordnungszahl 39 und wird als Übergangsmetall im Periodensystem klassifiziert. Es gehört zur Gruppe der Seltenen Erden und ist bekannt für seinen hohen Schmelzpunkt und seine hervorragende thermische Stabilität. Yttrium ist in der Luft relativ stabil und bildet eine schützende Oxidschicht, die eine weitere Oxidation verhindert. Es kommt typischerweise in Mineralien wie Xenotim und Monazit vor und wird hauptsächlich durch verschiedene chemische Prozesse gewonnen. Yttrium zeigt eine Vielzahl von Oxidationszuständen, wobei +3 der häufigste in Verbindungen ist. Es wird in verschiedenen Anwendungen eingesetzt, einschließlich Phosphoren für Farbfernsehgeräte und LED-Lampen, Supraleitern und als Legierungszusatz in Metallen zur Verbesserung der Festigkeit und Korrosionsbeständigkeit. Darüber hinaus werden Yttrium-Verbindungen in medizinischen Anwendungen genutzt, insbesondere in der Krebsbehandlung durch Radioisotope. Seine einzigartigen Eigenschaften machen Yttrium zu einem wertvollen Material in der Industrie und Technologie.

CAS:Kontrolliertes Produkt<p>Yttrium is a silvery-white, hard metal that is used primarily in alloys. Yttrium has an oxidation number of 3+, and it reacts with water vapor to form hydroxides. Yttrium can be found in wastewater treatment plants because it is resistant to corrosion by chlorine. It also binds to the monoclonal antibody and causes light emission, which can be observed using electrochemical impedance spectroscopy (EIS). The redox potential of yttrium is high, which allows it to oxidize other metals at lower concentrations than other metals would need to oxidize yttrium. Yttrium also has a coordination geometry of group P2, which means that its electrons are located in the same plane as the nucleus and are not as easily dislodged.</p>Formel:YReinheit:Min. 95%Molekulargewicht:88.91 g/mol
