An attempt to select the most suitable force-distance relation between a dislocation and the monovalent cation impurity was conducted among the three models: a square, a parabolic, and a triangular force-distance relations. These models are taken into account the Friedel relation. The grope for the most suitable model was carried out by the linear relationship of effective stress and temperature. However, it was difficult to select the most suitable of the three at 80 to 300 K for the two kinds of single crystals: KCl:Li+ (LiCl 0.5 mol% in the melt) and KCl:Na+ (NaCl 0.5 mol% in the melt). Critical emperature,Tc, at which the effective stress due to the impurities is zero was further obtained on the three force-distance relations for both the specimens.
