ABSTRACT:
A method for producing a cordierite body having high crystallinity and exhibiting excellent low thermal expansion property in a specific direction at a relatively low firing temperature comprises the steps of mixing and kneading a batch raw material containing halloysite particles and plate-shaped talc particles, anisostatically forming the batch raw material into a formed body to impart a planar orientation to the plate-shaped talc particles within the batch raw material and drying and firing the formed body.
