Zusammenfassung:The invention relates to a ceramic component containing silicon carbide and to the use of the component. The method for producing the ceramic component comprises 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 solventbeing different, c) drying or curing the impregnated green body, d) carbonizing the dried or cured green body, wherein a fine-pored, foam-like carbon skeleton is produced from the dried solvent or afine-pored, sponge-like carbon skeleton is produced from the cured resin system, e) silicizing the carbonated green body by infiltrating with liquid silicon. The ceramic component contains 70-95wt.% of SiC, 2-27wt.% of free si
