Cesium Iodide vs. Soda-lime Glass
Cesium iodide belongs to the non-glass optical ceramics classification, while soda-lime glass belongs to the glass and glass-ceramics. There are 13 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is cesium iodide and the bottom bar is soda-lime glass.
