POROUS CERAMIC MATERIAL HAVING A MACROPOROSITY CONTROLLED BY LAYERING PORE-FORMING AGENTS.

摘要

The invention relates to a porous ceramic material, including: a microstructure including a material with a crystalline xonotlite and/or tobermorite structure, said material being crystallized in the form of needles connected to each other so as to provide therebetween a pore diameter D95 that is greater than or equal to 0.4 μm and less than 5 μm, and a mean pore diameter D50 that is greater than or equal to 0.4 μm and less than 1.5 μm, preferably 0.4 to l μm; and a macrostructure consisting of a continuous and/or discontinuous layering of macropores.
