ABSTRACT:
A finely porous article is produced by a method which comprises preparing a colloidal liquid phase containing silica particles by the addition of an ion-exchange resin to an aqueous sodium silicate solution or a liquid phase by the addition of an ion-exchange resin to an aqueous silica colloid solution and the subsequent treatment of the resultant composite for removal of salt or acid therefrom, mixing the former colloidal liquid phase or the latter liquid phase with a smectite type mineral, and drying the resultant mixture.
