CAS 7631-86-9: Sílica

Descrição: Sílica, quimicamente conhecido como dióxido de silício (SiO2), é um composto que ocorre naturalmente e é abundante na crosta terrestre. É caracterizado por sua estrutura cristalina dura e é comumente encontrado em várias formas, incluindo quartzo, areia e vidro. Sílica é um sólido incolor, inodoro e insípido que é insolúvel em água e na maioria dos solventes orgânicos. Tem um alto ponto de fusão e excelente estabilidade térmica, tornando-o útil em aplicações de alta temperatura. Sílica exibe uma variedade de propriedades físicas, incluindo alta dureza e fragilidade, e é um mau condutor de eletricidade. Além de sua importância geológica, Sílica é amplamente utilizado em várias indústrias, incluindo construção, eletrônicos e produção de alimentos, muitas vezes como um preenchimento, abrasivo ou dessecante. Também é um componente essencial na fabricação de vidro e cerâmica. Embora geralmente considerado seguro, a inalação de poeira fina de Sílica pode representar riscos à saúde, levando a problemas respiratórios como silicose.
