Aluminum Titanate vs. Aluminum Nitride
Aluminum titanate belongs to the oxide-based engineering ceramics classification, while aluminum nitride belongs to the non-oxide engineering ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is aluminum titanate and the bottom bar is aluminum nitride.
