MICROREACTOR COMPRISING A POROUS CERAMIC MATERIAL

摘要

Product formed from a ceramic material, at least part of the said product not being formed from amorphous silica, comprising pores and satisfying the following criteria: (a')at least 70% bynumber of the said pores are tubular pores extending substantially parallel to each other in a longitudinal direction; (b')in at least one cross-section plane, -at least 30% by number of the pores have a section of convex hexagonal shape, these pores being known hereinbelow as "hexagonal pores", at least 80% by number of the said hexagonal pores having a roundness index of greater than 0.70, the roundness index being equal to the ratio SA/LA of the lengths of the small and long axes of the ellipse in which the said section is inscribed; -the mean size of the cross sections of the said pores is greater than 0.15µm and less than 25µm.
