Abstract

Procedimiento para fabricar una matriz cerámica porosa, comprendiendo dicho procedi miento: i) preparar una dispersión compuesta por agua, partículas refractarias, por lo menos un material orgánico formador de poros y un dispersante polimérico; ii) añadir un éster cíclico sensible al agua a la dispersión en una concentración de 1 a 10 × 10-5 mol/g de dispersión; iii) colocar la dispersión en un molde; iv) permitir o provocar que el éster cíclico se hidrolice para dar lugar a un aumento de la viscosidad de la mezcla lo que produce que solidifique y forme un bloque en bruto; v) separar el bloque en bruto del molde; y vi) calentar el bloque en bruto para eliminar el agua y quemar el material orgánico.
