Calcium Fluoride vs. Limestone
Calcium fluoride belongs to the non-glass optical ceramics classification, while limestone belongs to the natural stone. There are 10 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is calcium fluoride and the bottom bar is limestone.
