Abstract
(EN)
Provided are: a method for producing a ceramic article having a porous part and realizing improvement in mechanical strength of a molded article while obtaining high molding accuracy; and a ceramic article. This production method comprises: (i) a step for forming a powder layer by evenly spreading a powder of metal oxide that contains aluminum oxide as the main component; (ii) a step for melting and solidifying or for sintering the powder by irradiating the powder layer with an energy beam on the basis of shaping data; (iii) a step for causing a liquid that contains a zirconium component to be absorbed by a molded article having a porous part and being formed by repeating steps (i) and (ii); and (iv) a step for heating the molded article that has absorbed the liquid containing the zirconium component, wherein in the absorption step, the liquid is absorbed such that the proportion of the zirconium component among metal components contained in the porous part becomes 0.3-2.0 mol%.

L'invention concerne : un procédé de production d'un article en céramique ayant une partie poreuse et permettant une amélioration de la résistance mécanique d'un article moulé tout en obtenant une précision de moulage élevée ; et un article en céramique. Le procédé de production selon l'invention comprend : (i) une étape de formation d'une couche de poudre par étalement uniforme d'une poudre d'oxyde métallique qui contient de l'oxyde d'aluminium en tant que composant principal ; (ii) une étape de fusion et de solidification ou de frittage de la poudre par irradiation de la couche de poudre avec un faisceau d'énergie sur la base de données de mise en forme ; (iii) une étape pour amener un liquide qui contient un composant de zirconium à être absorbé par un article moulé ayant une partie poreuse et étant formé par répétition des étapes (i) et (ii) ; et (iv) une étape de chauffage de l'article moulé qui a absorbé le liquide contenant le composant de zirconium, dans l'étape d'absorption, le liquide étant absorbé de telle sorte que la proportion du composant de zirconium parmi les composants métalliques contenus dans la partie poreuse devienne de 0,3 à 2,0 % en moles.
