Abstract

La presente invención es concerniente con un método para la preparación de sílice precipitada que comprende la reacción de un silicato con un agente acidificante para obtener una suspensión de sílice precipitada (S1), seguida por una etapa de separación para obtener una retorta, una etapa de astillamiento de dicha retorta para obtener una suspensión de sílice precipitada (S2) y una etapa de secado de dicha suspensión, método en donde la etapa de astillamiento se lleva a cabo a una temperatura de entre 50 y 120°C.
