Abstract

Procédé de fabrication d’une mousse céramique frittée Procédé de fabrication d’une mousse céramique frittée suivant les étapes successives suivantes : a) préparation d'un mélange M contenant au moins une poudre céramique en suspension dans de l’eau, au moins un agent gélifiant et au moins un agent moussant, à une température de mélange supérieure à la température de gélification dudit agent gélifiant, b) cisaillement dudit mélange M à une température de moussage supérieure à ladite température de gélification, jusqu'à obtention d'une mousse intermédiaire, c) gélification de ladite mousse intermédiaire par refroidissement de ladite mousse intermédiaire à une température au moins deux fois plus faible que la température de gélification de l’agent gélifiant, en °C, d) séchage de ladite mousse gélifiée de manière à obtenir une préforme dont l’humidité après séchage est inférieure à 1%, e) cuisson de ladite préforme à une température supérieure à 1300°C et inférieure à 2300°C.
