Low Expansion Glass-ceramic vs. Forsterite

Low expansion glass-ceramic belongs to the glass and glass-ceramics classification, while forsterite belongs to the oxide-based engineering ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is low expansion glass-ceramic and the bottom bar is forsterite.
