CoorsTek SC-DSG (SC-35) Graphite Loaded Sintered Silicon Carbide
Categories: Ceramic; Carbide

Material Notes: Thermal Shock Delta Tc = 600°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.
