GRAPHITE-COATED SHAPED BODY MADE OF SINTERED SILICON CARBIDE
Shaped body based on polycrystalline SiC and having a density of greater than 90% of its theoretical density and an adherent graphite layer on its surface, wherein the graphite layer is crystalline, has a thickness of 0.1-100 µm and has been produced by thermal surface decomposition of the SiC after it has been sintered to closed porosity.
