Zinc Sulfide vs. Aluminum Titanate

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