Many kinds of engineering ceramics have been developed and used as parts of mechanical structures. These ceramics are often used as machine parts which are exposed to elevated temperatures. The strength distribution of those materials significantly depends upon the temperature. In this study, distribution characteristics of the flexural strength for alumina ceramics were examined at the temperatures of room temperature (RT), 800°C, 1000°C and 1200°C, respectively. Based on the temperature dependence of distribution parameters, the Probability-Strength-Temperature characteristics were quantitatively analysed. An analytical model for the temperature dependence of the strength distribution was finally proposed by introducing the defect sensitivity and its temperature dependence. Analytical results thus obtained were in good agreement with the experimental aspect of the strength distributions.
