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. 701 offers very good thermal shock resistance, good flexural strength, and 0–1% porosity due to its vitrified properties. This cordierite can self-glaze. It is suitable for applications such as commercial heater supports.
