Protection of graphite and graphite-containing materials from oxidation

“…It has been established that the dispersity of silicon particles as silicon undergoes crystal transformation at 1273 -1373 K is determined by conditions under which the sol was prepared. Under specifically controlled ambient conditions, b-SiC nanoparticles could be synthesized from atomic carbon and silicon monoxide [20]. Using a sol-gel technology, a dense intermediate corundum layer was developed that was reinforced with b-SiC nanoparticles and mullite whisker; this layer was an impermeable barrier for the diffusion of carbon into the oxide filler even at operating temperatures higher than 2000 K [9].…”
