CAS 7440-58-6

Afnio

Descrizione:

Afnio è un metallo di transizione con il simbolo chimico Hf e il numero CAS 7440-58-6. È caratterizzato dal suo alto punto di fusione, che è uno dei più alti tra tutti gli elementi, rendendolo utile in applicazioni ad alta temperatura. Afnio ha un aspetto grigio argenteo e presenta una lucentezza metallica. È noto per la sua eccellente resistenza alla corrosione, in particolare in ambienti acidi, grazie alla formazione di uno strato protettivo di ossido. Afnio ha una densità relativamente alta ed è spesso utilizzato nei reattori nucleari, poiché ha una forte capacità di assorbire neutroni. Inoltre, è utilizzato nella produzione di leghe ad alte prestazioni e nell'industria dei semiconduttori per le sue proprietà come materiale dielettrico. Afnio si trova tipicamente nei minerali di zirconio ed è estratto attraverso processi come la cristallizzazione frazionata. Il suo comportamento chimico è simile a quello dello zirconio e forma vari composti, incluso l'ossido di Afnio, che è significativo in elettronica e ottica. In generale, le proprietà uniche di Afnio lo rendono prezioso in varie applicazioni tecnologiche avanzate.

Hafnium is a chemical element with symbol Hf and atomic number 72. Hafnium is a lustrous, silvery gray, transition metal that has the highest melting point of all metals. It is chemically similar to zirconium and exhibits similar physical properties. The most common oxidation state of hafnium is +4, but compounds in oxidation states +2 and +3 exist as well. Hafnium has no biological role and its toxicity is low. Hafnium's potential applications include fabrication of semiconductors, electrodes for high-temperature gas sensors, nuclear control rods, and quantum computing devices.
