CAS 7440-03-1: Niobio
Descrizione:
Niobio, con il simbolo chimico Nb e il numero CAS 7440-03-1, è un metallo di transizione noto per il suo alto punto di fusione e la sua eccellente resistenza alla corrosione. È un metallo grigio argenteo, duttile e facilmente modellabile. Niobio è utilizzato principalmente nella produzione di leghe di acciaio ad alta resistenza, che migliorano la resistenza e la tenacità dei materiali utilizzati nella costruzione e nella manifattura. Ha una struttura cristallina cubica centrata sul corpo e presenta proprietà superconduttrici a basse temperature, rendendolo prezioso in applicazioni come macchine per risonanza magnetica e acceleratori di particelle. Niobio è anche resistente all'ossidazione e può formare uno strato di ossido protettivo, che contribuisce alla sua durabilità in vari ambienti. Inoltre, è relativamente raro nella crosta terrestre e si ottiene principalmente da minerali come columbite e pirocloro. Grazie alle sue proprietà uniche, Niobio gioca un ruolo significativo nella tecnologia moderna e nella scienza dei materiali.

CAS:Niobium sputtering target is used in high temperature engineering products. It is also used as an alloying agent for certain steels where it greatly improves the strength of the resulting material. It is also finds applications in atomic reactors due to its corrosion resistance and, when combined with either tin (Nb3Sn) or zirconium, it has a high degree of superconductivity.
