Abstract: Silver or silver oxide-doped silicic acid is claimed which is produced pyrogenically by flame oxidation or preferably flame hydrolysis. The dopants are added at 0.0001 wt.% to up to 20 wt.%, preferably 1-10000 ppm. The dopant is a salt (mixture) of Ag or a suspension of an Ag compound or metallic Ag or their mixture. The BET surface of the doped oxide is 1-600 (preferably 40-400) m /g. An Independent claim is included for the preparation of a silver or silver oxide pyrogenically doped oxide.

Abstract: A pyrogenic process is used to prepare alkali-doped silica particles. Particles produced by this process exhibit homogeneous doping, reduced agglomeration, greater stability and higher removal rates. Aqueous dispersions containing alkali-doped pyrogenic silica with average particle size less than 100 nm are used for polishing surfaces (CMP).

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.
