High-alumina Refractory vs. Alpha Quartz

High-alumina refractory belongs to the oxide-based engineering ceramics classification, while alpha quartz belongs to the non-glass optical ceramics. There are 5 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is high-alumina refractory and the bottom bar is alpha quartz.
