IEC 60672 Type C-530 Porous Cordierite
C-530 porous cordierite is a grade of cordierite. The graph bars on the material properties cards below compare C-530 porous cordierite to other oxide-based engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
