ABSTRACT:
The present invention is directed toward the improvement of the properties of cordierite sintered structures. The improvement consists essentially of heat treating the calcined kaolin component which when added to the batch of ray materials increases the thermal shock resistance and decreases the coefficient of thermal expansion.
