Aqueous dispersions comprises a cerium (Ce) oxide-doped pyrogenic silica, the Ce oxide having been obtained via an aerosol from a Ce salt solution or dispersion and the average particle diameter in the dispersion being below 100nm. An Independent claim is also included for the production of the dispersions by high-energy dispersion.
