A new SiC coating on carbon particles has been developed using SiO powders as the Si source by a chemical vapor reaction. Uniform SiC coating was obtained on individual particle with the thickness of 10 nm to 10 μm. The SiC coated carbon particles sintered by PECS exhibited unique microstructures with a 3D micro-network structure consisting of graphite grains covered with thin SiC grain boundaries. The sintered products at 2000°C showed a high bending strength of 150 MPa.
