Patent number: 11878944Abstract: A ceramic component containing silicon carbide and to the use of the component. The method for producing the ceramic component includes the following steps: a) providing a green body based on SiC, 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 solution or a fine-pored, sponge-like carbon skeleton is produced from the cured resin system.Type: GrantFiled: September 28, 2018Date of Patent: January 23, 2024Assignee: SGL CARBON SEInventors: Andreas Kienzle, Dominik Rivola, Oswin Oettinger, Blasius Hell, Philipp Modlmeir
