Abstract

The effect of impurities (Na+ and Cl ions) on the viscoelastic properties of ice is studied in the temperature interval 210–290 K. It is established that the heating of a sample to temperatures by 15–20 K lower than the melting point results in a considerable decrease of its shear modulus. The observed effect is ascribed to premelting processes. It is shown that the presence of Cl ions does not change the premelting temperature of ice, whereas the stress field arising around Na+ ions introduced into ice results in its variation. The dependence of the characteristic premelting temperature
