| Abstract: | The advantage of fast firing depends not only on the finer grain-size effect at the sintering temperature, but also on the smaller pore-size effect which results from the restricted pore growth. Pore growth due to the differential sintering during heating was observed to occur at relatively low temperature regions, and rapid passing through the region restricted the pore growth and enhanced the densification. |
