CVD Diamond vs. Aluminosilicate Glass

CVD diamond belongs to the non-oxide engineering ceramics classification, while aluminosilicate glass belongs to the glass and glass-ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is CVD diamond and the bottom bar is aluminosilicate glass.
