Graphite vs. Aluminum Nitride
Both graphite and aluminum nitride are non-oxide engineering ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.
For each property being compared, the top bar is graphite and the bottom bar is aluminum nitride.
