Zusammenfassung:There is disclosed a process for preparing porous ceramic granules, comprising (a) preparing a foam from an aqueous mixture of a particulate aluminosiliceous material and a fluxing material; (b) dividing the foam into discrete particles to form granules; and (c) calcining the granules at an elevated temperature such that sintering of the aluminosiliceous particles occurs.
