PROCESS FOR THE PREPARATION OF MOULDED ARTICLES FROM PYROGENICALLY PREPARED OXIDES |
| 摘要 |
<p>Pressed objects (slugs) of pyrogenically produced oxides such as SiO2, Al2O3 and TiO2 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.</p> |
