Graphite vs. CVD Diamond
Both graphite and CVD diamond are non-oxide engineering ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is graphite and the bottom bar is CVD diamond.
