ZA-12 vs. Calcium Fluoride
ZA-12 and calcium fluoride belong to fundamentally different material chemistries. ZA-12 is a metal, while calcium fluoride is a ceramic material. 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 ZA-12 and the bottom bar is calcium fluoride.
