Beryllia vs. Aluminosilicate Glass

Beryllia belongs to the oxide-based engineering ceramics classification, while aluminosilicate glass belongs to the glass and glass-ceramics. There are 6 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is beryllia and the bottom bar is aluminosilicate glass.
