A maior parte do sil\u00edcio \u00e9 usado industrialmente sem ser purificado e, de fato, muitas vezes com relativamente pouco processamento de sua forma natural.\u00a0O sil\u00edcio \u00e9 um ingrediente vital em ligas de alum\u00ednio, a\u00e7o e ferro.\u00a0\u00c9 adicionado como agente fundente para ligas de cobre.\u00a0Na forma de argila e areia, \u00e9 utilizada na fabrica\u00e7\u00e3o de tijolos e concreto;\u00a0\u00e9 um material refrat\u00e1rio valioso para trabalhos de alta temperatura, por exemplo, areias de moldagem para fundi\u00e7\u00f5es em aplica\u00e7\u00f5es de fundi\u00e7\u00e3o.\u00a0A s\u00edlica \u00e9 usada para fazer tijolo refrat\u00e1rio, um tipo de cer\u00e2mica.\u00a0Os minerais de silicato tamb\u00e9m est\u00e3o na cer\u00e2mica branca, uma importante classe de produtos geralmente contendo v\u00e1rios tipos de minerais de argila cozidos (filossilicatos de alum\u00ednio naturais).\u00a0Um exemplo \u00e9 a porcelana, que \u00e9 baseada no mineral silicato caulinita.\u00a0O vidro tradicional (vidro soda-cal \u00e0 base de s\u00edlica) tamb\u00e9m funciona de muitas das mesmas maneiras,\u00a0e tamb\u00e9m \u00e9 usado para janelas e cont\u00eaineres.\u00a0O sil\u00edcio met\u00e1lico hiperpuro e o sil\u00edcio hiperpuro dopado (dopagem com boro, f\u00f3sforo, g\u00e1lio ou ars\u00eanico) s\u00e3o usados \u200b\u200bem c\u00e9lulas solares, transistores e semicondutores.<\/span><\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
