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 at least one metaloxy radical and optionally further alkoxy and/or hydroxy radical(s) and at least one solvent, at least one surface-active substance or a mixture thereof, a process for producing the mixture, 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.
