Aluminum Titanate vs. Low Expansion Glass-ceramic
Aluminum titanate belongs to the oxide-based engineering ceramics classification, while low expansion glass-ceramic belongs to the glass and glass-ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is aluminum titanate and the bottom bar is low expansion glass-ceramic.
