| Abstract |
| Clay-based saggars, commonly used in the pottery industries in India,
can not stand more than 5 to 6 thermal cycles. With a view to understanding
the different parameters controlling the thermal shock resistance
property of fired ceramics, b!ldies containing 50% cordierite
grog-50% clay, 50% clay grog-50% clay and 50% cl~y grog-
50% cordierite were prepared with variations in grog s1zes. The
strength was measured after each thermal cycle.
From the studies, it could be inferred that by using preformed
cordierite, much longer life would be assured and a method for evaluating
thermal endurance of fired ceramics could be standardised. |
