Abstract: A product obtained by treating surface-modified, pyrogenically produced titanium dioxide with at least one ammonium-functional silane, such as by spraying the pyrogenically produced titanium dioxide with the at least one silane, alone or in ethanol solution, and tempering, and useful in the field of cosmetics in sunblocks, in toner powders, in paints and varnishes, in silicone rubber, as abrasives and polishes, for example, in the field of CMP.

Abstract: PURPOSE: Pyrogenic titanium dioxide granulates are provided which are useful as catalyst supports. CONSTITUTION: Such granulates based on pyrogenic titanium dioxide(TiO2) has an average particle diameter of 10 to 150 microns, a BET surface area of 25 to 100 m¬2/g, a pH of 3 to 6 and a tamped density of 400 to 1200 g/l. The granulates are obtainable by dispersing titanium dioxide into water and spray-drying the resulting dispersion, followed by salinization. The silanized granulates have an average particle diameter of 10 to 160 microns, a BET surface area of 15 to 100 m¬2/g, a pH of 3.0 to 9.0, a tamped density of 400 to 1200 g/l, and a carbon content of 0.3 to 12.0 wt%.
