Titanium Diboride vs. Alpha Quartz
Titanium diboride belongs to the non-oxide engineering ceramics classification, while alpha quartz belongs to the non-glass optical ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is titanium diboride and the bottom bar is alpha quartz.
