Material Notes:

Thermal Shock Delta Tc = 350°C - Thermal shock tests are performed by quenching samples in water from different elevated temperatures. Delta Tc is the change in temperature which results in a sharp decrease in the flexural strength of the sample.Data Provided by the manufacturer, CoorsTek, Inc.
