Method for manufacturing silicon carbide honeycomb structure, silicon carbide honeycomb structure, honeycomb filter, and catalyst-carrying honeycomb filter

摘要

There is provided a method for manufacturing a silicon carbide honeycomb structure. The method using a regeneration raw material regenerated from a recovered material derived from a starting raw material of a silicon carbide honeycomb structure generated in a manufacture process of a silicon carbide honeycomb structure. The regeneration raw material is recovered from a material constituting the silicon carbide honeycomb structure in a step after the starting raw material is fired. The regeneration raw material is added to the starting raw material to account for 50 mass% or less of the entire starting raw material as a part of the starting raw material after the average particle size of the regeneration raw material is controlled to be 5 to 100 µm, and the silicon carbide honeycomb structure is manufactured using the starting raw material.
