摘要

Disclosed is a process for producing a silicon-carbide-coated carbon base material in which the surface of a carbon base material such as graphite is coated with a silicon carbide coating film densely and uniformly. The process is characterized by comprising: a step of preparing a carbon base material which has, formed on the surface thereof, a base part composed of an SP2 carbon structure having no dangling bond and an edge part composed of an SP2 carbon structure having a dangling bond; and a step of reacting the surface of the carbon base material with an SiO gas in an atmosphere in which the temperature is 1400 to 1600°C and the pressure is 1 to 150 Pa to form silicon carbide, thereby producing a carbon base material coated with silicon carbide.
