Potassium Chloride vs. Silver Chloride
Both potassium chloride and silver chloride are non-glass optical ceramics. There are 14 material properties with values for both materials. Properties with values for just one material (1, 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 potassium chloride and the bottom bar is silver chloride.
