The commonly used theory of grain boundary migration with impurities was applied to doped ice annealed samples in order to obtain the until now unknown values of ice grain boundary thickness and the enthalpy of the interaction between impurities and the grain boundary.
The analyzed samples correspond to the previously reported studies of the grain boundary migration rate performed on ice bicrystals, obtained from 1 and 10 μmol l-1 (0. 02 and 0. 2 ppm) potassium chloride (KCl) water solutions annealed in the temperature range [-5°C ,-20°C] .
