Cer

Beschreibung:
Cer ist ein silberweißes, duktiles Metall, das zur Lanthanid-Serie des Periodensystems gehört, mit der Ordnungszahl 58 und der CAS-Nummer 7440-45-1. Es ist bekannt für seinen relativ hohen Schmelzpunkt und ist eines der häufigsten Seltenen Erden-Elemente. Cer zeigt eine Vielzahl von Oxidationszuständen, am häufigsten +3 und +4, die zu seinem vielfältigen chemischen Verhalten beitragen. Es oxidiert leicht in der Luft und bildet eine schützende Oxidschicht und kann bei erhöhten Temperaturen mit Wasser reagieren. Cer-Verbindungen, wie Cer-oxid, werden häufig als Katalysatoren in Automobilkatalysatoren und in verschiedenen industriellen Anwendungen, einschließlich der Glaspolitur und als Bestandteil in Phosphoren für die Beleuchtung, verwendet. Darüber hinaus hat Cer Anwendungen in der Metallurgie und als Zusatz in bestimmten Legierungen, um deren Eigenschaften zu verbessern. Seine einzigartigen Eigenschaften machen Cer zu einem wichtigen Element sowohl in industriellen als auch in technologischen Kontexten.

  • Cerium

    CAS:
    <p>Cerium is a rare earth metal and has been studied for its minimal toxicity. Cerium has been shown to be biocompatible and can be used in the treatment of inflammatory diseases. Cerium oxide nanoparticles have been shown to have minimal toxicity and are being studied as a possible drug delivery system for the treatment of osteoarthritis. Cerium has also been shown to have antioxidant activity, which may be due to its ability to scavenge reactive oxygen species or chelate iron. Cerium oxide nanoparticles have also been shown to have potential application in wastewater treatment, as they are able to adsorb organic matter, heavy metals, and radioactive elements.</p>
