Abstract
There is disclosed a process for preparing a porous inorganic material. The process comprises preparing a cellular aluminosilicate material by foaming or spray drying an aqueous suspension of the material. The cellular material is calcined, leached with hydroxide to remove silica, dewatered and dried to leave a porous, cellular ceramic material.
