Cadmium Telluride vs. Mullite

Cadmium telluride belongs to the non-glass optical ceramics classification, while mullite belongs to the oxide-based engineering ceramics. There are 10 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is cadmium telluride and the bottom bar is mullite.
