Title: Production method of silicon carbide particles

Abstract: The present invention is to provide a production method of silicon carbide particles of high quality without generating a sulfur compound in the carbonizing and baking processes. More concretely, a production method of silicon carbide particles comprising a step of mixing at least one kind of a silicon compound, which is liquid at ordinary temperatures, an organic compound having a functional group, which generates carbon by heating and is liquid at ordinary temperatures, and a polymerization or crosslinking catalyst, which can homogeneously dissolve with the organic compound to obtain a mixture, a step of homogeneously solidifying the mixture to obtain solid matter, and a step of heating and baking the solid matter in a non-oxidizing atmosphere, wherein the catalyst is a compound consisting of carbon atoms, hydrogen atoms and oxygen atoms, and has a carboxyl group.
