:Praseodimio
Descrizione:
Praseodimio è un elemento chimico con il simbolo Pr e numero atomico 59, appartenente alla serie dei lantanidi della tavola periodica. È un metallo bianco argenteo che è relativamente morbido e malleabile, mostrando una lucentezza brillante quando appena tagliato. Praseodimio è noto per le sue proprietà uniche, inclusa la sua capacità di formare una varietà di stati di ossidazione, principalmente +3 e +4, che contribuiscono al suo comportamento chimico diversificato. È moderatamente reattivo, annerendosi nell'aria e reagendo con l'acqua per formare idrossido di Praseodimio. Questo elemento è utilizzato principalmente nella produzione di forti magneti permanenti, così come in varie leghe e ceramiche, in particolare nelle industrie del vetro e della ceramica dove conferisce un colore giallo. Inoltre, i composti di Praseodimio sono utilizzati nella produzione di alcuni tipi di laser e come catalizzatori in varie reazioni chimiche. A causa della sua abbondanza relativamente bassa nella crosta terrestre, Praseodimio è tipicamente estratto da minerali come bastnasite e monazite.
