CAS 7631-86-9: Sílice
Descripción:
Sílice, conocido químicamente como dióxido de silicio (SiO2), es un compuesto que ocurre de forma natural y que es abundante en la corteza terrestre. Se caracteriza por su estructura cristalina dura y se encuentra comúnmente en varias formas, incluyendo cuarzo, arena y vidrio. Sílice es un sólido incoloro, inodoro e insípido que es insoluble en agua y en la mayoría de los disolventes orgánicos. Tiene un alto punto de fusión y una excelente estabilidad térmica, lo que lo hace útil en aplicaciones a altas temperaturas. Sílice exhibe una variedad de propiedades físicas, incluyendo alta dureza y fragilidad, y es un mal conductor de electricidad. Además de su importancia geológica, Sílice se utiliza ampliamente en diversas industrias, incluyendo la construcción, la electrónica y la producción de alimentos, a menudo como relleno, abrasivo o deshidratante. También es un componente esencial en la fabricación de vidrio y cerámica. Aunque generalmente se considera seguro, la inhalación de polvo fino de Sílice puede representar riesgos para la salud, provocando problemas respiratorios como la silicosis.
