Abstract
A method includes the following steps: a) the production of a slip including more than 4% and less than 50% of ceramic particles and including: b) a first particulate fraction including of orientable particles having a median length L'50 and representing more than 1% of the ceramic particles, and c) a second particulate fraction having a median length D50 at least ten times shorter than L′50 and representing more than 1% of the ceramic particles, the first and second particulate fractions together representing more than 80% of all of the ceramic particles, in volume percentages based on the total quantity of ceramic particles; d) oriented freezing of the slip by moving a solidification front at a lower speed than the speed of encapsulation of the ceramic particles; e) elimination of the crystals of the solidified liquid phase of the block; and f) optionally sintering.
