Cesium Bromide vs. Steatite

Cesium bromide belongs to the non-glass optical ceramics classification, while steatite belongs to the oxide-based engineering ceramics. There are 9 material properties with values for both materials. Properties with values for just one material (19, 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 cesium bromide and the bottom bar is steatite.
