Forsterite vs. Glass-bonded Mica
Forsterite belongs to the oxide-based engineering ceramics classification, while glass-bonded mica belongs to the glass and glass-ceramics. There are 9 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 forsterite and the bottom bar is glass-bonded mica.
