C-820 Magnesia Ceramic vs. High-silica Glass
C-820 magnesia ceramic belongs to the oxide-based engineering ceramics classification, while high-silica glass belongs to the glass and glass-ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is C-820 magnesia ceramic and the bottom bar is high-silica glass.
