Abstract

a. Procédé de fabrication d'une structure alvéolaire en céramique exempte de fissures présentant une multiplicité de canaux paralléles s'étendant au travers de celle-ci. b. Ce procédé se caractérise en ce qu'il consiste : à combiner des poudres constituant le matériel de départ de céramique ; à ajouter de l'eau et un alcool polyhydrique dans un rapport en poids de 85 : 15-5 : 95 aux poudres de céramique et à pétrir le mélange résultant; à façonner la mixture ainsi obtenue en une structure alvéolaire; à sécher la structure alvéolaire façonnée à une température qui permet l'évaporation de l'eau mais qui ne permet pas l'évaporation de l'alcool polyhydrique de manière à éliminer l'eau ; à chauffer la structure alvéolaire à une température qui permet l'évaporation de l'alcool polyhydrique de manière à éliminer ledit alcool polyhydrique; et ensuite, à soumettre la structure alvéolaire à la cuisson. c. La structure alvéolaire en céramique obtenue par ce procédé peut notamment être utilisée en tant que substrat de catalyseur pour la purification de divers gaz d'échappement ou en tant que noyau pour échangeur de chaleur.
