Abstract

Cette invention concerne, dans un mode de réalisation, une céramique de titanate d'aluminium contenant du titanate d'aluminium comme composant principal, et de l'oxyde de cérium comme composant secondaire. La pièce moulée d'un mode de réalisation de l'invention comporte plusieurs canaux (110a, 110b) qui sont quasiment parallèles les uns aux autres et qui sont divisés par des séparations poreuses (120), lesdites séparations (120) contenant la céramique de titanate d'aluminium.
