Granules based on titanium dioxide with the characteristics: Average particle diameter: 10 to 150µm BET surface area: 25 to 100 m2/g PH 3 to 6 Compacted density: 400 to 1,200 g/1 They are prepared by dispersing titanium dioxide in water and spray-drying and silanisin. In the silanised form, the granules have the following characteristics: Average particle diameter: 10 to 160µm BET surface area: 15 to 100 m2/g pH: 3.0 to 9.0 Compacted density: 400 to 1,200g/l Carbon content: 0.3 to 12.0 wt.% The granules are used, inter alia, as catalyst supports, in cosmetics, as sun screens, in silicone rubber, in toning powder, in lacquers and colorants, as grinding and polishing agents and as a raw material for producing glass and ceramics.
