Abstract: A process for foaming ceramic foams, in which the ceramic foams are produced from a precursor or a mixture of precursors which contain at least one ceramic-forming element and liberates at least one volatile reaction product during an inorganic gelation process. In one embodiment, foaming is based on a precursor containing crystals of the AlCl3(Pri2O) complex. The decomposition of the initial precursor produces polymerizing species dissolved in liquid isopropyl chloride. The solvent and growing AlOxCly(OPri)z species are mixed homogeneously so that the boiling point of the solution is raised above the boiling point of the pure isopropyl chloride. Polymerization takes place in the liquid until a critical polymer size is attained, whereupon a phase separation into polymer rich and solvent rich regions occurs. Since the expelled solvent is suddenly above its boiling point, bubbles start forming instantly.

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.
