Silicon Carbide vs. Forsterite

Silicon carbide belongs to the non-oxide engineering ceramics classification, while forsterite belongs to the oxide-based engineering ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is silicon carbide and the bottom bar is forsterite.
