Method for manufacturing honeycomb structure

Abstract

A process for producing a honeycomb structure, which comprises adding, to a particulate ceramic raw material, a fatty acid salt-containing dispersing agent and at least water, kneading the mixture to obtain a puddle, and extruding the puddle, wherein the fatty acid salt constituting the dispersing agent comprises: a fatty acid salt having a fatty acid moiety of 12 carbon atoms, in an amount of 45 to 75% by mass (in terms of the value of the fatty acid moiety), a fatty acid salt having a fatty acid moiety of 14 carbon atoms, in an amount of 10 to 30% by mass (in terms of the value of the fatty acid moiety), a fatty acid salt having a fatty acid moiety of 16 carbon atoms, in an amount of 5 to 15% by mass (in terms of the value of the fatty acid moiety), and a fatty acid salt having a fatty acid moiety of other carbon atoms, in a residual amount. This process allows production of a honeycomb structure of superior shape at a high productivity and can reduce the load acting on the extruder used.
