Abstract
L'invention concerne un procédé de fabrication d'une céramique poreuse (1) comprenant de l'oxyde de zirconium, de cérium et/ou d'hafnium, ainsi qu'une céramique (1) fabriquée selon ledit procédé. Selon le procédé, le zirconium, le cérium et/ou l'hafnium sont fondus avec au moins un métal plus noble et au moins un élément ayant une affinité pour l'oxygène jusqu'à l'obtention d'une masse fondue; la masse fondue est refroidie jusqu'à solidification; la masse fondue solidifiée est soumise à une oxydation interne, le zirconium, le cérium et/ou l'hafnium ainsi que ledit au moins un élément ayant une affinité pour l'oxygène s'oxydant, et, pour finir, le métal plus noble est éliminé de sorte qu'il reste la céramique poreuse.
