Zusammenfassung:Pressed titanium dioxide is produced by intensively mixing pyrogenically prepared titanium dioxide in the presence of deionised water with a humectant and/or a base and/or, if appropriate, a binder and/or, if appropriate, a forming aid and/or, if appropriate, a pore former, extruding the resulting mass at pressures of between 5 and 100 bar to give mouldings, drying the mouldings at temperatures between 50 and 120 DEG C and then calcining them for 1 to 5 hours in ambient air at temperatures from 400 to 700 DEG C.
