ANORGANISCHE VERBUNDMETALLOXIDKUGELN MIT GROSSEN PORENVOLUMEN, IHRE HERSTELLUNG UND IHRE VERWENDUNGEN BEI ADSORPTION UND CHROMATOGRAPHIE

摘要

The present invention provides porous mineral oxide beads which have large pore volumes and enhanced stability. The beads are based on a tetravalent metal oxide, such as zirconia, titania or hafnia. These highly porous beads are produced from a mixture of tetravalent mineral oxides, mineral pore inducing agents which are oxides or salts of trivalent metals, and optional binders. The porous mineral beads can be filled with a polymer gel and used for adsorption and chromatography applications.
