Abstract

La presente invención se refiere a un método para preparar sílice precipitada que comprende la reacción de un silicato con un agente acidificante para obtener una suspensión de sílice precipitada, y a continuación un paso de separación para obtener una masa húmeda y un paso de secado de dicha masa húmeda, método en el cual, entre el paso de separación y el paso de secado, se lleva a cabo un paso de compactación de dicha masa húmeda a una presión superior a 10 bar.
