CVD Diamond vs. Sandstone
CVD diamond belongs to the non-oxide engineering ceramics classification, while sandstone belongs to the natural stone. There are 13 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is CVD diamond and the bottom bar is sandstone.
