High-silica Glass vs. Magnesium Titanate

High-silica glass belongs to the glass and glass-ceramics classification, while magnesium titanate belongs to the oxide-based engineering ceramics. There are 8 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is high-silica glass and the bottom bar is magnesium titanate.
