Abstract
Experimental data of Eu2+ distribution in EuCl2-doped KCl ingots are a nalyzed. After setting the relation between variable distribution coef ficient and the dopant concentration in the melt, the simulation of th e dopant zone-leveling for various molten zone widths is performed. It is shown that owing to the decrease of the distribution coefficient c aused by increasing dopant concentration in the molten zone, the numbe r of the zone passes after which the dopant concentration levees off u ndergoes significant reduction.
