Zircon vs. Hexagonal Boron Nitride

Zircon belongs to the oxide-based engineering ceramics classification, while hexagonal boron nitride belongs to the non-oxide engineering ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is zircon and the bottom bar is hexagonal boron nitride.
