Abstract
The association of Ni2+ cations with cation vacancies was followed by measuring the electric conductivity of NaCl: NiCl2 crystals. It was found that this association reaction may be described over the whole temperature range of 20 to 620 ‡C by a simple Stasiw-Teltow model with an association enthalpy of 0·62 eV and association entropy of 6·3 k. The precipitation effects in crystals were negligible above the room temperature up to the Ni2+ concentration of 100 ppm.
