The resistance of ceramics to thermal shock can be characterized using either a parameter of their resistance to fracture R or the critical temperature difference ΔT cT c(Bi). It is demonstrated that a correlation exists between the values ofR and ΔT c. Experiments were performed on alumina-based ceramic materials (99.8 and 86% Al2O3), glass-bonded mullite, and a borosilicate glass. Three equations were used to describe the dependence of the critical temperature difference on the Biot number. A relationship between the critical temperature difference and the parameterR was considered and the best correlation between the values ofR and ΔT c was established using statistical analysis techniques. It is shown that the correlation can be described satisfactorily in terms of a linear dependence.
