Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a silicon carbide fine powder, by which the silicon carbide fine powder having a uniform particle size, especially the silicon carbide fine powder having an average particle size of <=1 μm can be easily produced. SOLUTION: This method for producing the silicon carbide fine powder includes a mixing process for obtaining a mixed powder by mixing a silicon powder comprising a silicon particles containing oxygen in an amount of >=0.2 mass % and a carbon powder and a heating process for synthesizing the silicon carbide fine powder by heating the mixed powder.

Thereby, it becomes possible to carry out a liquid phase reaction of silicon and carbon sufficiently at a temperature not lower than the melting point of silicon. Accordingly, a silicon carbide fine powder having a uniform particle size, e.g. a silicon carbide fine powder having an average particle size of <=1 μm can be synthesized.
