Abstract

a. Procédé de fabrication de pièces en céramique. b. Procédé caractérisé en ce qu'on mélange à sec des matériaux céramiques en poudre dont la nature et la granulométrie sont adaptées aux caractéristiques des pièces à obtenir, et on enrobe les grains de ce mélange céramique avec une solution, dans un solvant non aqueux et de préférence volatil, d'une composition organique polymérisable, puis, avec le mélange céramique ainsi enrobé, on remplit des moules et on provoque la polymérisation rapide de la composition organique polymérisable, par l'action d'un catalyseur fluide injecté dans le mélange céramique à l'intérieur du moule, et/ou par l'action de la chaleur sur ce mélange céramique. c. L'invention s'applique notamment à la fabrication des isolants de bougies d'allumage.
