Abstract

The present invention relates to a stable mixture comprising surface-modified particles which are obtained by reacting metal oxide or semimetal oxide particles with at least one compound selected from among silicon-comprising compounds bearing one, two or three alkoxy radicals and at least one solvent, at least one surface-active substance or a mixture thereof, the use of these particles in systems in which they are brought into contact with at least one solvent, where the mass ratio of solvent to modified particle is greater than 500, and also the use of these particles in agglomeration-deagglomeration cycles.
