ABSTRACT:
Highly gas-tight rotary cordierite heat regenerator is formed of a honeycomb structural body having a porosity of 20-45% and mainly consisting of cordierite, and open pores of the partition walls defining channels of the honeycomb structural body are sealed with a filler thereto, the difference of thermal expansion between the honeycomb structural body and the filler being less than 0.1% at 800.degree. C. The honeycomb structural body is made by preparing fired segments thereof, sealing the open pores of the partition walls with the filler thereof, bonding the segments with a ceramic bonding material, and firing the bonded segments.
