  • Patent number: 7374787
    Abstract: An aqueous dispersion, having a silicon dioxide powder having a silicon dioxide content of 10 to 60 wt.%, wherein the aqueous dispersion is stable in the pH range of 2 to 6, the aqueous dispersion additionally contains at least one compound, which is at least partially soluble in aqueous solution in the pH range 2 to 6 in the form of polyvalent cations, these being stable in a silicate-like environment as an anionic component of the particle surface of the silicon dioxide powder, the quantity of cation-providing compound in relation to the surface of the silicon dioxide is 0.001 to 0.1 mg cation-providing compound/m2 silicon dioxide surface, the cation-providing compound being calculated as the oxide, and the zeta potential of the aqueous dispersion has values of less than or equal to zero.

  • Patent number: 6752864
    Abstract: Granules based on pyrogenically prepared silicon dioxide doped with aluminum oxide by means of an aerosol, which granules have the characteristic data: mean particle diameter: from 10 to 150 &mgr;m BET surface area: from 25 to 100 m2/g pH value: from 3 to 6 tamped density: from 400 to 1200 g/l They are produced by dispersing in water pyrogenically prepared silicon dioxide doped with aluminum oxide by means of an aerosol, spray drying the dispersion, and optionally carrying out tempering and/or silanization. In the silanized form, the granules have the following characteristic data: mean particle diameter: from 10 to 160 &mgr;m BET surface area: from 15 to 100 m2/g pH value: from 3 to 9 tamped density: from 400 to 1200 g/l carbon content: from 0.3 to 12.0 wt.
