NOVELTY - Fabricating a sintered product comprises: (a) preparing a slip comprising a set of ceramic particles suspended in a liquid phase; (b) optionally casting the slip in a mold and/or removing air bubbles present in the slip; (c) oriented freezing the slip to form a block of frozen slip and to form crystals of a solidified liquid phase separated by walls; (d) optionally demolding the block to obtain a macroporous preform; (e) removing the crystals of liquid phase of the block; (f) optionally debinding the preform; and (g) optionally sintering the preform to obtain a sintered product.    USE - The method is useful for fabricating a sintered product, which is useful in a device including a ceramic electrochemical cell, a fuel cell, preferably a solid oxide fuel cell, an intermediate temperature solid oxide fuel cell and a protonic ceramic fuel cell, a liquid or gaseous fluid filtration element, a microstructure storage unit, a catalyst carrier, a heat exchanger, a thermal insulation, a distributor for conveying the fluid, preferably gas distributor, a drop separator or an air treatment plant, a battery, preferably an electrolyte battery, a supercondensor, a moisture adsorber, a micro-combustion chamber, a transducer, a displacement sensor, an echographic probe, a support unit and a sintering muffle (all claimed).    ADVANTAGE - The sintered product has improved mechanical properties such as modulus of elasticity, toughness and resistance to rupture.    DETAILED DESCRIPTION - Fabricating a sintered product comprises: (a) preparing a slip comprising a set of ceramic particles suspended in a liquid phase; (b) optionally casting the slip in a mold and/or removing air bubbles present in the slip; (c) oriented freezing the slip by movement of a solidification front at a speed, which is less than a speed of encapsulation of the ceramic particles, to form a block of frozen slip and to form crystals of a solidified liquid phase separated by walls having an average thickness that is less than or equal to 1 of an average thickness of orientable ceramic particles (104); (d) optionally demolding the block by sublimation to obtain a macroporous preform; (e) removing the crystals of solidified liquid phase of the block; (f) optionally debinding the macroporous preform; (g) optionally sintering the macroporous preform to obtain a sintered product; and (h) optionally machining and/or impregnating the sintered product. The amount of set of ceramic particles is more than 4 vol.% and less than 50 vol.%. The set of ceramic particles comprises more than 1 vol.% of orientable ceramic particles made of a material comprising an oriented function, and non-orientable ceramic particles. The fraction of non-orientable ceramic particles has a median length, which is less than ten times a median length of the orientable ceramic particles if the set of ceramic particles comprises less than 80 vol.% of orientable ceramic particles. The ceramic particles are totally or partially replaced by equivalent amounts of precursors. The shape of orientable ceramic articles is determined so that orientation (P) of the particles under the effect of freezing has an intensity, which varies according to a considered direction. An INDEPENDENT CLAIM is included for the sintered product comprising macroscopic frustoconical tubular pores that extend parallel to each other in a longitudinal direction, where each pore is defined by walls comprising 50 vol.% of orientable ceramic particles and the walls between the pores comprise 5 vol.% of particles.
