Ceramic carbon composite material, method for producing ceramic carbon composite material, ceramic-coated ceramic carbon composite material, and method for producing ceramic-coated ceramic carbon composite material

摘要

Achieved is a ceramic carbon composite material and a ceramic-coated ceramic carbon composite material which are lighter than ceramics and excellent in at least one of properties including oxidation resistance, resistance to dust generation, heat conductivity, electrical conductivity, strength, and denseness. The ceramic carbon composite material is a ceramic carbon composite material in which an interfacial layer of a ceramic is formed between carbon particles of or containing graphite. The ceramic carbon composite material can be produced by forming a green body from ceramic-coated powder in which the surfaces of carbon particles of or containing graphite are coated with individual ceramic layers and sintering the green body.
