Abstract

DC60 (24/03/52) The fabrication consists of a granular substance containing a) micronized silicic acid (A) with a mean particle size from 2 to 15 microns, specific volume of Hole from 0.3 to 2.0 ml / g, Specific surface (BET) from 200 to 1000 m2 / g. In concentrations from 5 to 60% by weight or b) hydrates or dehydrates aluminosilicates (B) containing sodium and / or - potassium and / or calcium cations. With particle sizes between 1 and 25 microns in concentrations from 5 to 75% by weight and c) organic additive mixtures (C) in concentrations from 25 to 95% by weight but at least 5% (measured by suction Oil absorbing), which is more than necessary to fill holes of silicic acid and the gaps between silicic acid particles. And all aluminosilicate particles The invention consists of a granular substance consisting of a) micronized silicic acid gel (A) with a mean magnitude from 2 to 15 microns, specific hole volumes from 0.3 to 2.0 ml / g, Specific surface (BET) from 200 to 1000 m (2 / g in a concentration from 5 to 60% by weight or b) hydrate or aluminosilicate dehydrate (B) consisting of sodium And / or potassium and / or calcium cation With particle sizes between 1 and 25 microns in concentrations from 5 to 75% by weight and c) organic additive mixtures (C) in concentrations from 25 to 95% by weight but at least 5% (measured by suction Oil absorbing), which is more than necessary to fill holes of silicic acid. And the space between the particles of silicic acid And all aluminosilicate particles
