Zinc Selenide vs. Machinable Glass-ceramic
Zinc selenide belongs to the non-glass optical ceramics classification, while machinable glass-ceramic belongs to the glass and glass-ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.
For each property being compared, the top bar is zinc selenide and the bottom bar is machinable glass-ceramic.
