Abstract: Pyrogenic silica doped with alumina by means of aerosol is based on pyrogenic silica produced by flame oxidation or flame hydrolysis and contains 1 x 10 to 20 wt.% dopant. Pyrogenic silica doped with alumina by means of aerosol is based on pyrogenic silica produced by flame oxidation or flame hydrolysis and contains 1 x 10 to 20 wt.% dopant. The amount of dopant (preferably) is in the 1-10,000 ppm range and the dopant is aluminum (Al) salt(s), a suspension of an Al compound and/or Al. The doped oxide has a BET surface area of 5-600 m /g. Independent claims are also included for (a) the production of the doped pyrogenic silica; (b) mixtures of 0.01-100% of this product and other pyrogenic or precipitated silica, bentonite and/or other fillers normally used in the paper industry.
