By the atomic absorption method one measures the light absorption by the vapor of the investigated element as a function of the temperature of the evaporating surface. To measure vapor pressure the authors use cadmium selenide of the purity grade, which was recrystallized by sublimitation. The optical density of the vapor over cadmium selenide was determined in the temperature range 820-890 K. Using atomic spectroscopy the vapor pressure of cadmium over cadmium selenide was determined in dichromium cadmium tetraselenide with different amounts of deviation from stoichiometry at 790-880 deg. The results are compared with the literature data.
