Abstract
A process for preparing aluminium oxide beads from alumina hydrogel, which comprises polymerizing, in a hot and substantially water-immiscible fluid, an aqueous mixture comprising alumina hydrogel and alumina hydrosol and a water-soluble monomer whose uncross-linked polymer is water-soluble or forms a gel, this mixture being dispersed as droplets into a hot fluid in which substantial polymerization of the monomer occurs.
