Aluminum Titanate vs. Mullite
Both aluminum titanate and mullite are oxide-based engineering ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.
For each property being compared, the top bar is aluminum titanate and the bottom bar is mullite.
