| It has been shown that divalent impurities (Sr2+ ,Eu2+) harden the NaCl monocrystals intensively. For the solution treated samples the effective obstacles and interaction mechanisms are nearly the same for both crystal systems. In contrary, because of some differences in the solubility limit and in the clustering phenomena as well, different interaction mechanisms determine-the crystal strength attainable in as-received samples. |
