Material Notes:
Thermal Shock Delta Tc = 200°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.Corrosion: Although all Coors Ceramics are highly resistant to chemical attack, Coors recommends obtaining specific application data from Coors before design finalization.Data Provided by the manufacturer, Coors Ceramics Co.
