Zirconia vs. Magnesium Fluoride
Zirconia belongs to the oxide-based engineering ceramics classification, while magnesium fluoride belongs to the non-glass optical ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.
For each property being compared, the top bar is zirconia and the bottom bar is magnesium fluoride.
