ABSTRACT:
A method for producing a cordierite body having a lower coefficient of thermal expansion and excellent thermal shock resistance which comprises the steps of mixing and kneading a batch raw material containing plate-shaped talc particles and non-plate shaped particles of other ceramic material, anisostatically forming the mixed batch raw material so as to impart a planar orientation to the plate-shaped talc particles and drying and firing the obtained formed body. By firing the plate-shaped talc particles, the shrinkage of the cordierite body can be decreased.
