Abstract
ABREGE DESCRIPTIF
Procédé de préparation industrielle de céramiques isolantes à porosité controlée consistant à mélanger des grains concassés et une poudre fine constituée d'oxydes des métaux du groupe IIa, IIIb, IVb de la classification périodique des éléments, puis à fritter ce mélange à température modérée en présence d'un fluorure. Céramique obtenue par ce procédé
constituée, notamment oe grains d'alumine mélangés à de la poudre d'alumine de la proportion des grains dans la poudre fine dépendra la porosité de la céramique. Application à la fabrication des pièces pour pompes pour métaux liquides cor-rosifs tels que l'aluminium.
