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