C-820 Magnesia Ceramic vs. Zinc Sulfide
C-820 magnesia ceramic belongs to the oxide-based engineering ceramics classification, while zinc sulfide belongs to the non-glass optical ceramics. There are 8 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 C-820 magnesia ceramic and the bottom bar is zinc sulfide.
