Aluminum Titanate vs. Zinc Sulfide

Aluminum titanate belongs to the oxide-based engineering ceramics classification, while zinc sulfide belongs to the non-glass optical ceramics. There are 6 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 aluminum titanate and the bottom bar is zinc sulfide.
