METHOD FOR PRODUCING A CERAMIC FOAM HAVING REINFORCED MECHANICAL STRENGTH FOR USE AS A SUBSTRATE FOR A CATALYST BED

摘要

A method for manufacturing ceramic foam, including impregnating polymer foam having an open porosity with a first suspension of ceramic particles in a solvent; drying the impregnated polymer foam; heat treating the dried polymer foam by thermally decomposing the dried polymer foam; unbinding the organic compounds contained in the polymer foam, and pre-sintering the ceramic particles contained in the polymer foam; impregnating the polymer foam with a second suspension of ceramic particles in a solvent; drying the polymer foam, sintering the ceramic particles contained in the polymer foam.
