Abstract
There is provided a method for manufacturing a silicon carbide based honeycomb structure, the method using, as a part of a starting material, a recycled raw material recycled from a recovered material generated in a process for manufacturing the silicon carbide based honeycomb structure and derived from a starting material for a silicon carbide based honeycomb structure; wherein the recycled raw material is pulverized to have an average particle size of 10 to 300 μm. According to the present invention, structure defects such as voids or coarse particles, which have been problems upon manufacturing a silicon carbide based honeycomb structure, are hardly formed, and a silicon carbide based honeycomb structure having excellent strength and uniform heat conductivity can be obtained. In addition, since a once kneaded material is used as a part of a starting material, the time for kneading can be shortened.
