Barium Fluoride vs. GM-120 Glass Ceramic

Barium fluoride belongs to the non-glass optical ceramics classification, while GM-120 glass ceramic belongs to the glass and glass-ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is barium fluoride and the bottom bar is GM-120 glass ceramic.
