Aluminum Nitride vs. Marble

Aluminum nitride belongs to the non-oxide engineering ceramics classification, while marble belongs to the natural stone. There are 12 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is aluminum nitride and the bottom bar is marble.
