Aluminum Titanate vs. Fused Silica

Aluminum titanate belongs to the oxide-based engineering ceramics classification, while fused silica belongs to the glass and glass-ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.

For each property being compared, the top bar is aluminum titanate and the bottom bar is fused silica.
