Graphite-coated shaped body made of sintered silicon carbide

摘要

Shaped body based on polycrystalline SiC and having a density of greater than 90% of its theoretical density and graphite layer on its surface, wherein the graphite layer is crystalline, has a thickness of 0.1-100 mum and has been produced by thermal surface decomposition of the SiC after it has been sintered to closed porosity.
