Title (EN) CERAMIC COMPONENT
(FR) COMPOSANT CÉRAMIQUE
(DE) KERAMISCHES BAUTEIL
Abstract:
(EN) The invention relates to a ceramic component, wherein the component contains 20 - 60 wt.% SiC, 5 - 40 wt.%, free silicon and 10 - 65 wt.% free carbon. The invention also relates to the use of the component. The method for producing the ceramic component comprises the following steps: a) providing a green body based on carbon, which has been produced by means of a 3D-printing method, b) impregnating the green body with a solution selected from the group consisting of a sugar solution, a starch solution or a cellulose solution, or a resin system comprising a mixture containing at least one resin, at least one solvent and at least one curing agent, the at least one resin and the at least one solvent being different, c) drying or curing the impregnated green body, d) carbonising the dried or cured green body, wherein a fine-pored, foam-like carbon skeleton is produced from the dried solvent or a fine-pored, sponge-like carbon skeleton is produced from the cured resin system, e) silicizing the carbonated green body by infiltrating with liquid silicon.
(FR) L'invention concerne un composant céramique, le composant contenant de 20 à 60 % en poids de SiC, de 5 à 40 % en poids de silicium libre et de 10 à 65 % en poids de carbone libre, ainsi que l'utilisation du composant. Le procédé de réalisation comprend les étapes suivantes consistant à : a) fournir un corps cru à base de carbone qui a été produit par un procédé d'impression 3D; b) imprégner le corps cru avec une solution choisie dans le groupe comprenant une solution de sucre, une solution d'amidon et une solution de cellulose, ou avec un système de résine comprenant un mélange contenant au moins une résine, au moins un solvant et au moins un agent durcisseur, l'au moins une résine et l'au moins un solvant étant différents; c) sécher ou durcir le corps cru imprégné; d) carboniser le corps cru séché ou durci, un réseau carboné mousseux à pores fins étant formé à partir de la solution séchée ou un réseau carboné spongieux à pores fins étant formé à partir du système de résine durci; e) silicatiser le corps cru carbonisé par infiltration avec du silicium liquide.
(DE) Die vorliegende Erfindung betrifft ein keramisches Bauteil, wobei das Bauteil, 20 bis 60 Gew.-% SiC, 5 bis 40 Gew.-%, freies Silizium und 10 bis 65 Gew.-% freien Kohlenstoff enthält, sowie die Verwendung des Bauteils. Das Verfahren zur Herstellung umfasst die folgenden Schritte: a) Bereitstellen eines Grünkörpers auf Basis von Kohlenstoff, welcher mittels eines 3D-Druckverfahrens hergestellt worden ist, b) Imprägnieren des Grünkörpers mit einer Lösung ausgewählt aus der Gruppe bestehend aus einer Zuckerlösung, einer Stärkelösung oder einer Celluloselösung, oder einem Harzsystem umfassend eine Mischung enthaltend mindestens ein Harz, mindestens ein Lösungsmittel und mindestens einen Härter, wobei das mindestens eine Harz und das mindestens eine Lösungsmittel unterschiedlich sind, c) Trocknen oder Aushärten des imprägnierten Grünkörpers, d) Karbonisieren des getrockneten oder ausgehärteten Grünkörpers, wobei aus der getrockneten Lösung ein feinporiges, schaumartiges Kohlen stoff gerüst oder dem gehärteten Harzsystem ein feinporiges, schwammartiges Kohlenstoffgerüst entsteht, e) Silizieren des karbonisierten Grünkörpers durch Infiltration mit flüssigem Silizium.
