ABSTRACT:
A process for the preparation of bulk foams which comprises contacting ceramic foam particles with a hydrophobic material to form impregnated and/or coated ceramic foam particles with hydrophobic properties. The impregnated and/or coated ceramic foam particulate material is mixed with a ceramic binding material with or without an organic binder in an aqueous composition solution to form a castable and pressable mixture. The castable and pressable mixture is cast, and optionally pressed, in a mold to form a wet green body, which is in turn dried to form a dried green body, and is then fired and sintered to form a bulk shape foam article.
