Zirconio

Descrizione:

Zirconio è un metallo di transizione con il simbolo Zr e numero atomico 40. È caratterizzato dal suo alto punto di fusione, eccellente resistenza alla corrosione e forte affinità per l'ossigeno, che porta alla formazione di uno strato di ossido protettivo. Zirconio è un metallo grigio argenteo che è relativamente duttile e può essere facilmente fabbricato in varie forme. Si trova principalmente in natura sotto forma di silicato di Zirconio ed è spesso estratto attraverso la riduzione del cloruro di Zirconio. Questo elemento è notevole per la sua bassa sezione d'urto per la cattura di neutroni termici, rendendolo prezioso in applicazioni nucleari, in particolare nei componenti dei reattori e nel rivestimento del combustibile. Inoltre, Zirconio è utilizzato nella produzione di ceramiche, materiali dentali e varie leghe grazie alla sua resistenza e resistenza al calore e alla corrosione. I suoi composti, come il diossido di Zirconio, sono utilizzati in una gamma di applicazioni, inclusi materiali refrattari e come opacizzanti nelle ceramiche. In generale, le proprietà uniche di Zirconio lo rendono un materiale importante in vari campi industriali e tecnologici.
