CAS 7440-21-3
:Silicio
Descrizione:
Silicio, con il numero CAS 7440-21-3, è un elemento metalloide che gioca un ruolo cruciale in varie industrie, in particolare nell'elettronica e nella scienza dei materiali. È caratterizzato dal suo lucido aspetto metallico e dalla sua natura fragile nella forma cristallina. Silicio ha un alto punto di fusione ed è un cattivo conduttore di elettricità a temperatura ambiente, ma la sua conduttività aumenta significativamente quando viene drogato con impurità, rendendolo un materiale semiconduttore fondamentale. È abbondante nella crosta terrestre, trovato principalmente sotto forma di silicati e biossido di Silicio. Silicio è essenziale nella produzione di vetro, ceramica e calcestruzzo, ed è un componente chiave nella fabbricazione di celle solari e chip per computer. Inoltre, Silicio mostra una capacità di legame tetravalente, permettendogli di formare legami covalenti stabili con altri elementi, il che è vitale per creare vari composti a base di Silicio. La sua versatilità e le sue proprietà uniche fanno di Silicio una pietra miliare della tecnologia moderna e dell'ingegneria dei materiali.
