SiO 2-containing dispersions having high salt stability |
| abstract |
The invention relates to an aqueous dispersion comprising surface-modified hydrophilic silica particles, wherein: A) the surface-modified hydrophilic silicon dioxide particles contain aluminum atoms and hydrocarbon radicals, a) the aluminum atoms are bonded to the silicon atoms of the particle surface via oxygen atoms, b) the hydrocarbon radicals contain silicon atoms bonded to the carbon atoms of the hydrocarbon radicals, c) the average particle diameter d in the dispersion 50 From 40 to 200nm, preferably from 60 to 150nm, and B) the dispersion has a pH of 8 or more. |
