C-820 Magnesia Ceramic vs. Silica Aerogel

Both C-820 magnesia ceramic and silica aerogel are oxide-based engineering ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is C-820 magnesia ceramic and the bottom bar is silica aerogel.
