The hardening of NaCl crystals induced by the presence of europium ions has been systematically investigated in two regions of temperatures (below 343 K and above 473 K) as function of the aggregation and/or precipitation stage of the dopant. The kinetics of Eu 2+ — clustering was followed by taking the δσ 0 ( t an ) — data at various annealing temperatures T an . The results have been discussed in frames of the available theoretical models and compared with those obtained previously from OA‐ and ITC‐data.
