Method for manufacturing honeycomb structure

Abstract

A method for manufacturing a honeycomb structure includes preparing a honeycomb formed body by extruding a green body comprising a ceramic raw material, a pore-forming material, a binder and a dispersion medium through a die that defines opening shapes of the plurality of cells; drying the honeycomb formed body to obtain a honeycomb dried body; and firing the honeycomb dried body to obtain a honeycomb fired body in which a thickness of the partition walls is 50 μm or more and 210 μm or less, and a porosity of the partition walls is 45% to 60%; wherein the pore-forming material contains crosslinked starch and an acrylic polymer, and the green body contains 1.0 parts by mass or more of crosslinked starch with the proviso that a P content is less than 0.2 parts by mass, with respect to 100 parts by mass of the ceramic raw material.
