| abstract |
The present invention provides surface-modified particles obtained by reacting metal or semimetal oxide particles with one or more compounds selected from silicon-containing compounds having at least one metaloxy radical and optionally further alkoxy and / or hydroxy radical (s). And in a stable mixture containing one or more solvents, one or more surface-active substances or mixtures thereof, methods of making the particles, systems in which the particles are in contact with one or more solvents (mass ratio of solvent to modified particles is greater than 500). It relates to the use of the particles, and to the use of the particles in an agglomeration-atomization cycle. |
