CVD Diamond vs. Silver Bromide

CVD diamond belongs to the non-oxide engineering ceramics classification, while silver bromide belongs to the non-glass optical ceramics. There are 11 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is CVD diamond and the bottom bar is silver bromide.
