CVD Diamond vs. Baria-alkali-silica Glass

CVD diamond belongs to the non-oxide engineering ceramics classification, while baria-alkali-silica 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 (16, in this case) are not shown.

For each property being compared, the top bar is CVD diamond and the bottom bar is baria-alkali-silica glass.
