Abstract
La presente invencion se refiere a un procedimiento para la produccion de un aerogel de silice por medio de un procedimiento sol-gel, en donde en primer lugar se forma un liogel a una presion inferior a 40 bar y el liogel se convierte en un aerogel, caracterizado porque para la formacion del liogel, se mezclan entre si dos soles precursores que contienen precursores a base de silicio de manera continua mediante un sistema de alimentacion e inmediatamente tras el mezclado, se introducen en un dispositivo de reaccion, en donde un primer sol de precursor presenta un valor de pH acido o pH basico, y el segundo sol de precursor presenta un valor de pH distinto del primer sol de precursor. Tambien se refiere a un dispositivo de produccion. Dichos aerogeles son utiles como materiales aislantes.
