The main conclusions are as follows: (1) For the pure Al2O3, the thermal shock resistance index, after respectively 10 times, 20 times, 30 times, 40 times, 50 times of the thermal shock at 600 ℃, was between 23-30, and the fluctuation is very small; after successive thermal shock at 200-600 ℃ the thermal shock resistance index was between 22-30and the fluctuation is very small, too. It can be seen from the results that the effect of thermal shock system on thermal shock resistance index of pure Al2O3 is very small; (2) For 7 wt% SiC/Al2O3, the index of thermal shock resistance at 600 ℃ is 35-46 and the index of thermal shock resistance of successive thermal shock at 200-600 ℃ is 39-43, changing smoothly. It can be seen from the results that the effect of thermal shock system on thermal shock resistance index of 7 wt% SiC/Al2O3 is very small; (3) The...
