High-silica Glass vs. CVD Diamond
High-silica glass belongs to the glass and glass-ceramics classification, while CVD diamond belongs to the non-oxide engineering ceramics. There are 7 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 high-silica glass and the bottom bar is CVD diamond.
