Potassium Bromide vs. Low Expansion Glass-ceramic
Potassium bromide belongs to the non-glass optical ceramics classification, while low expansion glass-ceramic belongs to the glass and glass-ceramics. There are 12 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 potassium bromide and the bottom bar is low expansion glass-ceramic.
