Process for the preparation of synthetic silicates, characterized in that a organosol of freshly prepared monomeric silicic acid is reacted with a finely divided metal hydroxide in such an amount that the pH of the medium becomes instantaneously greater than 7, forming a gel that is transformed rapidly in a fine organic dispersion, which does not comprise more silica in the synergetic liquid, and then this organic dispersion is subjected to evaporation and drying.
