This tutorial paper explains the maximum likelihood method for Weibull analysis of mechanical strength of ceramic materials and how strength scales with area under stress. Weibull parameters for a variety of infrared window materials are presented. C

ZrW 2 O 8 is known for its isotropic negative thermal expansion over a wide of range of temperature from −272 to 777 °C. However, ZrW 2 O 8 melts incongruently at 1257 °C and is stable only over a short temperature interval between 1105 and 1257

Mechanical strength measurements of transparent ceramic window material coupons are customarily fit to a Weibull equation that describes the strength and its distribution. Predictions of window lifetime under stress are commonly based on slow crack g
