内容: | A low thermal expansion cordierite ceramic honeycomb is obtained by controlling crystal phases in such a manner that a cordierite crystal phase is not lower than 60% and an indialite crystal phase is not greater than 30%, wherein a sum of the cordierite crystal phase and the indialite crystal phase is not lower than 85%. Moreover, to this end, a method of producing the low thermal expansion cordierite ceramic honeycomb, having the steps of mixing raw materials and forming agents to obtain a raw materials batch, extruding and drying the raw material batch to obtain a formed body, and sintering the formed body, is characterized in that, during the sintering step, a temperature descending rate at least from a maximum temperature to 1300 DEG C is not greater than 100 DEG C/hour. |
