The strength retained after thermal shock was analysed theoretically and the probability of crack occurrence of ceramics was predicted using the Weibull statistical theory of fracture. For the purpose of verification of this proposed analysis, thermal shock tests on three kinds of ceramics using water as the quenching medium were performed. As a result, analytical results were found to be in good agreement with results of thermal shock tests. Furthermore, the critical quenching temperature difference was defined as the mean value of crack occurrence quenching temperature differences. Consequently, these proposed analytical results were also in good agreement with results of critical quenching temperature differences obtained by thermal shock tests, performed by quenching in water and liquid sodium.
