Abstract

Procedimiento de preparación de sílice precipitada que comprende la reacción de un silicato con un agente acidificante para obtener una suspensión de sílice precipitada (S1), seguida de una etapa de separación para obtener una torta, de una etapa de desaglomeración de dicha torta para obtener una suspensión de sílice precipitada (S2) y de una etapa de secado de esta suspensión, procedimiento en el que la etapa de desaglomeración se efectúa a una temperatura comprendida entre 50 y 120ºC.
