Abstract
La présente invention concerne un comprimé qui convient pour produire un corps structural en nid d'abeille de productivité élevée dans lequel un produit d'étanchéité et des parois traversantes sont complètement frittés. Le comprimé de l'invention (100) est doté d'un corps à structure cylindrique en nid d'abeille (70) présentant de multiples trous traversants approximativement parallèles (70a), et un produit d'étanchéité (70b) qui bouche une extrémité des trous traversants (70a). Le corps à structure cylindrique (70) a une première extrémité et une seconde extrémité approximativement perpendiculaires aux trous traversants (70a) ; certains des trous traversants (70a) sont bouchés par un produit d'étanchéité (70b) à la première extrémité et sont ouverts à la seconde extrémité, et les autres trous traversants (70a) sont bouchés par le produit d'étanchéité (70b) à la seconde extrémité et ouverts à la première extrémité. Le produit d'étanchéité (70b) contient une céramique, et le corps à structure cylindrique (70) contient une poudre de matière première céramique, ladite céramique étant à base de titanate d'aluminium et/ou de cordiérite, et le taux de retrait du matériau d'étanchéité pendant le frittage est de 80 à 100 % du taux de retrait des parois de séparation.
