Baria-alkali-silica Glass vs. Silicon Carbide

Baria-alkali-silica glass belongs to the glass and glass-ceramics classification, while silicon carbide 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 baria-alkali-silica glass and the bottom bar is silicon carbide.
