Method of producing cordierite honeycomb structure

摘要

A method of producing a cordierite honeycomb structure includes: preparing clay containing a cordierite raw material having an aspect ratio of 1.5 or more; forming the clay to prepare a formed product of a honeycomb shape; drying the formed product to prepare a dried honeycomb product; and firing the dried honeycomb product to prepare a cordierite honeycomb structure. The production method can obtain a cordierite honeycomb structure capable of suppressing formation of cracks during firing.
