:Silice
Descrizione:
Silice, chimicamente noto come biossido di silicio (SiO2), è un composto che si verifica naturalmente ed è abbondante nella crosta terrestre. È caratterizzato dalla sua struttura cristallina dura ed è comunemente trovato in varie forme, tra cui quarzo, sabbia e vetro. Silice è un solido incolore, inodore e insapore che è insolubile in acqua e nella maggior parte dei solventi organici. Ha un alto punto di fusione e un'eccellente stabilità termica, rendendolo utile in applicazioni ad alta temperatura. Silice presenta una gamma di proprietà fisiche, tra cui alta durezza e fragilità, ed è un cattivo conduttore di elettricità. Oltre alla sua importanza geologica, Silice è ampiamente utilizzato in vari settori, tra cui costruzione, elettronica e produzione alimentare, spesso come riempitivo, abrasivo o disidratante. È anche un componente essenziale nella produzione di vetro e ceramica. Sebbene generalmente considerato sicuro, l'inalazione di polvere fine di Silice può comportare rischi per la salute, portando a problemi respiratori come la silicosi.
