An extruded, honeycombed, monolithic fired ceramic whose primary crystal phase is cordierite and whose microstructure is characterized by a greater than random orientation of the anisotropic cordierite crystallites with their low expansion direction aligned substantially parallel to the plane of the webs of the monolith. The axial expansion coefficient of the honeycomb, with composition near that of stoichiometric cordierite, may be as low as 5.5 x10<->7 in./in./ DEG C. or lower in the range of 25 DEG -1000 DEG C. |
