Cordierite vs. High-alumina Refractory

Both cordierite and high-alumina refractory are oxide-based engineering ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is cordierite and the bottom bar is high-alumina refractory.
