Thermal Shock of Ceramic Material: Comparison of Resistance Parameter with the Critical triangle open T Values triangle open Tc=triangle open Tc(Bi) of Ceramic Materials

摘要

Thermal shock resistance of ceramic material can be characterized by using resistance parameters or critical temperature difference. Correlation between fracture resistance parameter. R and critical temperature difference, triangle open Tc was presented for four products (99 percent Al_2O_3 , 86 percent Al_2O_3, mullite and glass). Six equations representing dependence critical temperature difference on Biot number were used. Comparison of critical temperature difference as a function of Biot number with R parameter was also discussed. Statistical analysis was used to determine correlation between R parameter and critical temperature difference. This method showed that finear dependance was acceptibile to use in comparison R parameter with critical triangle open Tc values.
