Silicon Carbide vs. Infrared Transmitting Glass
Silicon carbide belongs to the non-oxide engineering ceramics classification, while infrared transmitting glass belongs to the glass and glass-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 silicon carbide and the bottom bar is infrared transmitting glass.
