Infrared Transmitting Glass vs. Silicon Carbide
Infrared transmitting glass belongs to the glass and glass-ceramics classification, while silicon carbide belongs to the non-oxide engineering ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is infrared transmitting glass and the bottom bar is silicon carbide.
