GM-120 Glass Ceramic vs. Zinc Sulfide
GM-120 glass ceramic belongs to the glass and glass-ceramics classification, while zinc sulfide belongs to the non-glass optical ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is GM-120 glass ceramic and the bottom bar is zinc sulfide.
