Graphite vs. High-silica Glass

Graphite belongs to the non-oxide engineering ceramics classification, while high-silica glass belongs to the glass and glass-ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is graphite and the bottom bar is high-silica glass.
