Abstract
Preparation of a slip including more than 4% and less than 50% of ceramic particles and including more than 1% of orientable ceramic particles made of a material including an oriented function, as volume percentage on the basis of the set of ceramic particles, wherein the fraction of non-orientable ceramic particles has a median length less than ten times the median length of the orientable ceramic particles if the set of ceramic particles includes less than 80%, as volume percentage, of orientable ceramic particles, oriented freezing of the slip by movement of a solidification front at a speed less than the speed of encapsulation of the ceramic particles; elimination of the crystals of solidified liquid phase of said block, optionally, sintering.
