Method of manufacturing honeycomb structure and silicon carbide particle for manufacturing the same

1. A method of manufacturing a honeycomb structure, comprising:

adding water to silicon carbide particles and kneading the same into a kneaded raw material, the silicon carbide having an average particle diameter of not less than 2 μm and not more than a honeycomb rib thickness×0.23 and with a logarithmic standard deviation of a particle size distribution of not less than 0.15 and not more than 0.40;

extruding the kneaded raw material by extrusion into a honeycomb extruded body; and

drying, calcining, and firing the extruded body.

2. The method of manufacturing a honeycomb structure according to claim 1 , wherein the logarithmic standard deviation of the particle size distribution was not less than 0.17 and not more than 0.40.

3. The method of manufacturing a honeycomb structure according to claim 1 , wherein a content of the silicon carbide is not less than 50 wt %.

4. The method of manufacturing a honeycomb structure according to claim 1 , wherein a proportion of particles with a particle diameter of not less than half the honeycomb rib thickness is less than 5 wt %.

5. Silicon carbide particles for manufacturing a honeycomb structure by extrusion, wherein

an average particle diameter is not less than 2 μm and not more than a honeycomb rib thickness×0.23 and a logarithmic standard deviation of a particle size distribution is not less than 0.15 and not more than 0.40.
