Potassium Bromide vs. CVD Diamond
Potassium bromide belongs to the non-glass optical ceramics classification, while CVD diamond belongs to the non-oxide engineering ceramics. There are 13 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is potassium bromide and the bottom bar is CVD diamond.
