Infrared Transmitting Glass vs. Ferrite
Infrared transmitting glass belongs to the glass and glass-ceramics classification, while ferrite belongs to the oxide-based engineering ceramics. There are 9 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 ferrite.
