Forsterite vs. Potassium Bromide

Forsterite belongs to the oxide-based engineering ceramics classification, while potassium bromide belongs to the non-glass optical ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is forsterite and the bottom bar is potassium bromide.
