Abstract

Process for the manufacture of a mesoporous product comprising the following successive steps: a) preparation of a slip comprising: a solvent an additive more than 4% as percentage by volume based on the slip of a powder formed of ceramic particles b) oriented freezing of the slip so as to form a block comprising ice crystals separated by walls c) removal of the ice crystals from said frozen slip block optionally removed from the mold so as to obtain a porous preform d) removal of the additive so as to obtain a preformed mesoporous product the additive and the amount of additive being chosen so that the additive is present in a mesopore forming micellar phase in said walls more than 25% by volume of said ceramic particles exhibiting a size less than twice the size of the micelles of said mesopore forming micellar phase.
