Abstract

La présente invention concerne un procédé de fabrication d'un filtre en nid d'abeille au cours duquel un corps en nid d'abeille façonné (100) est produit en façonnant de l'argile contenant un matériau céramique, en frittant le corps en nid d'abeille façonné (100) pour obtenir un corps en nid d'abeille fritté, en broyant la paroi périphérique extérieure du corps en nid d'abeille fritté pour obtenir un corps en nid d'abeille fritté et broyé et en mettant en place une paroi de revêtement périphérique extérieure à la périphérie extérieure du corps en nid d'abeille fritté et broyé pour obtenir le filtre en nid d'abeille. Dans une coupe du corps en nid d'abeille façonné (100) réalisée dans le sens vertical par rapport à son axe central, si la direction d'une cloison (2) allant du centre (11) vers une paroi périphérique extérieure (4) est la direction « 0° » et si une partie au niveau de laquelle une droite (12) parallèle à la direction 0° croise la paroi périphérique extérieure (4) constitue une « partie de direction 0° » (13), le corps en nid d'abeille façonné (100) lorsqu'il est soumis au frittage possède une partie broyée (6) qui est obtenue par broyage de la paroi périphérique extérieure (4) et qui est située dans la paroi périphérique extérieure (4) et dans une zone d'une largeur de 10 à 100 mm comprenant une « partie de direction 45° » (15) définie en référence à la « direction 0° ». Ce procédé peut éviter la formation d'une fissure dans le corps en nid d'abeille façonné lors du frittage.
