C-820 Magnesia Ceramic vs. Infrared Transmitting Glass
C-820 magnesia ceramic belongs to the oxide-based engineering ceramics classification, while infrared transmitting glass belongs to the glass and glass-ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.
For each property being compared, the top bar is C-820 magnesia ceramic and the bottom bar is infrared transmitting glass.
