NOVELTY - Product formed from a ceramic material, at least part of the product not being formed from amorphous silica, comprises pores.    USE - The product is useful for preparing device selected from a ceramic electrochemical cell, fuel cell, filtration element of liquid or gaseous fluid, storage microstructure, catalyst support, heat exchanger, heat insulator, fluid distributor, drop separator or trickle block for air processing plant, battery, supercapacitor, moisture adsorber, and combustion microchamber (claimed).    ADVANTAGE - The invention provides porous products that have good mechanical properties, and in particular good compression strength.    DETAILED DESCRIPTION - Product formed from a ceramic material, at least part of the product not being formed from amorphous silica, comprises pores, where it satisfies the following criteria: (a) at least 70% by number of the pores are frustoconical tubular pores extending substantially parallel to each other in a longitudinal direction; (b) in at least one cross-section plane, the mean size of the cross sections of the pores is greater than 0.15 mu m and less than 300 mu m; (c) in at least one cross-section plane, at least 50% by number of the pores have a convexity index Ic of greater than 87%, the convexity index of a pore being equal to the ratio of Sp/Sc of the surface areas Sp and Sc delimited by the perimeter and by the convex envelope of the pore, respectively. INDEPENDENT CLAIMS are:    (1) a method for manufacturing porous product comprising: (a) preparation of a slip comprising, as a volume percentage, more than 4% of a powder of ceramic particles suspended in an aqueous liquid phase, the liquid phase comprising a crystal growth activator; (b) optionally, pouring of the slip into a mould and/or removal of the air bubbles contained in the slip; (c) oriented freezing of the slip so as to form a block comprising an assembly of ice crystals each having an elongated frustoconical tubular shape; (d) optionally, stripping of the block of frozen slip from the mould; (e) removal of the ice crystals from the frozen block of slip, optionally stripped from the mould, preferably by sublimation, so as to obtain a porous perform; (f) optionally, removal of binder from the porous preform obtained at the end of step (e); (g) optionally, sintering of the porous preform obtained at the end of step (e) or (f) so as to obtain a porous sintered product; and (h) optionally, machining and impregnation of the porous sintered product;    (2) product that is manufactured or that may have been manufactured according to the method; and    (3) a device selected from a ceramic electrochemical cell, a fuel cell, a filtration element of a liquid or gaseous fluid, a storage microstructure, a catalyst support, a heat exchanger, a heat insulator, a fluid distributor, a drop separator or a trickle block for an air processing plant, a battery, a supercapacitor, a moisture adsorber, a combustion microchamber, where the device comprises the product.
