Abstract
"This work presents the results obtained in the researches for synthesis of new polymer composites and their use for the preparation of ceramic powders and ceramic porous products. New inorganic- organic hydrogels were prepared by the copolymerization of acrylic acid with N, N'- methylene bis acrylamide in concentrated slurries of kaoline or alumina and mixtures of them. The hydrogels were used to prepare ceramic foams by gel casting. The ceramic foams prepared from these hydrogel precursors by the burning of the polymer can be used for waste gases purification (filtration of hot gases from power plants). The hydrodynamic characteristics of new ceramic foams were also assessed. "
