Gallium Arsenide vs. Ferrite

Gallium arsenide belongs to the non-glass optical ceramics classification, while ferrite belongs to the oxide-based engineering ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is gallium arsenide and the bottom bar is ferrite.
