摘要： The invention relates to an architecture comprising ceramic or metallic foam, characterized in that the foam has at least one continuous and/or discontinuous, axial and/or radial porosity gradient ranging from 10 to 90%, and a pore size from 2 ppi to 60 ppi, and in that the architecture has a micro structure comprising specific area ranging between 0,1 to 30 m
2 /g, a grain size between 100 nm and 20 microns and a skeleton densification above 95%. One process to obtain this architecture can be based on the preparation of a ceramic foam with porosity gradient comprising: choosing at least one polymeric sponge, impregnation of the polymeric sponge by a ceramic slurry, drying of the impregnated sponge, pyrolysing the organics including the polymeric sponge, and sintering, and characterized in that we realize a pre-step to obtain a continuous and/or discontinuous porosity gradient.
