:Praseodym
Beschreibung:
Praseodym ist ein chemisches Element mit dem Symbol Pr und der Ordnungszahl 59, das zur Lanthanid-Serie des Periodensystems gehört. Es ist ein silber-weißes Metall, das relativ weich und formbar ist und beim frischen Schneiden einen hellen Glanz zeigt. Praseodym ist bekannt für seine einzigartigen Eigenschaften, einschließlich seiner Fähigkeit, eine Vielzahl von Oxidationszuständen zu bilden, hauptsächlich +3 und +4, die zu seinem vielfältigen chemischen Verhalten beitragen. Es ist mäßig reaktiv, läuft in der Luft an und reagiert mit Wasser, um Praseodym-Hydroxid zu bilden. Dieses Element wird hauptsächlich in der Herstellung von starken Permanentmagneten sowie in verschiedenen Legierungen und Keramiken verwendet, insbesondere in der Glas- und Keramikindustrie, wo es eine gelbe Farbe verleiht. Darüber hinaus werden Praseodym-Verbindungen in der Herstellung bestimmter Arten von Lasern und als Katalysatoren in verschiedenen chemischen Reaktionen verwendet. Aufgrund seiner relativ geringen Häufigkeit in der Erdkruste wird Praseodym typischerweise aus Mineralien wie Bastnäsit und Monazit gewonnen.
