Zircon vs. Silicon Carbide

Zircon belongs to the oxide-based engineering ceramics classification, while silicon carbide belongs to the non-oxide engineering ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

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