The microhardness measurements have been made on pure crystals of KCl, RbCl and mixed crystals of K 1− x Rb x Cl. Microhardness varies non‐linearly with composition being maximum near at the eqimolar composition. Microhardness values calculated from lattice parameter data are in good agreement with experimental data. The difference in the size of the ion constituting the mixed system is responsible for the internal strains giving rise to imperfections and inturn responsible for the non‐linear variation of microhardness with composition.
