Document Type and Number:
WIPO Patent Application WO/2002/079116
Kind Code:
A1
Abstract:
A method for manufacturing a honeycomb structure, wherein a particulate law material for ceramics is mixed and kneaded with a dispersant containing a fatty acid salt and at least water to prepare a body and the body is extruded and formed, characterized in that the fatty acid salt constituting the dispersant comprises 45 to 75 mass % (in terms of fatty acid moieties) of a fatty acid salt having a fatty acid moiety of 12 carbon atoms, 10 to 30 mass % (in terms of fatty acid moieties) of a fatty acid salt having a fatty acid moiety of 14 carbon atoms, and 5 to 15 mass % (in terms of fatty acid moieties) of a fatty acid salt having a fatty acid moiety of 16 carbon atoms. The method allows the manufacture of a honeycomb structure excellent in easiness in the step of being formed, with high productivity, in combination with the reduction of the load on an apparatus for forming the honeycomb structure.
