Calcium Fluoride vs. ZA-12
Calcium fluoride and ZA-12 belong to fundamentally different material chemistries. Calcium fluoride is a ceramic material, while ZA-12 is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (26, in this case) are not shown.
For each property being compared, the top bar is calcium fluoride and the bottom bar is ZA-12.
