CAS 7440-48-4: Kobalt

Beschreibung: Kobalt ist ein Übergangsmetall mit dem chemischen Symbol Co und der CAS-Nummer 7440-48-4. Es zeichnet sich durch sein hartes, glänzendes und silbergraues Aussehen aus. Kobalt ist bekannt für seinen hohen Schmelzpunkt und seine hervorragende Beständigkeit gegen Oxidation und Korrosion, was es in verschiedenen industriellen Anwendungen wertvoll macht. Es zeigt magnetische Eigenschaften und wird häufig in der Herstellung von hochfesten Legierungen, Batterien und Katalysatoren verwendet. Kobalt ist auch ein essentielles Spurenelement in biologischen Systemen und spielt eine entscheidende Rolle bei der Bildung von Vitamin B12. In Bezug auf das chemische Verhalten kann Kobalt in mehreren Oxidationszuständen existieren, wobei +2 und +3 die häufigsten sind. Es bildet leicht Komplexe mit verschiedenen Liganden, was zu seiner Vielseitigkeit in der Koordinationschemie beiträgt. Allerdings können Kobalt-Verbindungen in bestimmten Formen toxisch sein, was eine sorgfältige Handhabung und Regulierung in industriellen und Laborumgebungen erforderlich macht. Insgesamt machen die einzigartigen Eigenschaften von Kobalt es zu einem wichtigen Element sowohl in technologischen als auch in biologischen Kontexten.
