Potassium Bromide vs. Graphite
Potassium bromide belongs to the non-glass optical ceramics classification, while graphite belongs to the non-oxide engineering ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is potassium bromide and the bottom bar is graphite.
