Abstract
Pressed objects (slugs) of pyrogenically produced oxides such as SiO.sub.2, Al.sub.2 O.sub.3 and TiO.sub.2 are produced using a silica sol and water. As molding assistants thereby there is employed a polyhydric alcohol, e.g. glycerine or sorbitol. The water can be added adsorbed on a pyrogenically produced hydrophobized silica. The pressed object obtained can be used inter alia as catalyst carrier.
