The purpose of the authors paper is refinement of the limit of the homogeneity region of cadmium selenide. The method of extraction of cadmium into the vapor phase was used to determine the cadmium content in cadmium selenide. At 870/sup 0/K the equilibrium of the cadmium selenide crystals during saturation by cadmium was monitored according to the reproducibility (in the range of +/-15%) of the results of experiments of different durations (30, 46, 62, and 192 h). Since at 870/sup 0/K the equilibrium was established in 30 h, at higher temperatures the duration of the annealing was assumed to be 30 h. In addition, in experiments at 1270 and 1370 K, crystals with thicknesses from 200 to 1500 ..mu..m were saturated simultaneously. The solubility of cadmium in CdSe was found to be 0.00053-0.00071 at. % at 870/sup 0/K, 0.0073-0.0113 at. % at 1170/sup 0/K, 0.022 at. % at 1270 K, 0.038 at. % at 1320/sup 0/K, and 0.044 at. % at 1370/sup 0/K.itrified
