Material Notes:
Cordierites have low coefficients of thermal expansion and excellent resistance to thermal shock. They offer a range of thermal expansion, mechanical strength, and porosity criteria. They excel as cost-effective extruded and dry-pressed forms. Sikor® S offers higher compressive strength with slightly lower thermal shock resistance than other cordierites.
