Investigation of the saturated vapor pressure of zinc, selenium, and zinc selenide

Temperature dependences of the saturated vapor pressure of elemental zinc (873-1234 K) and selenium (730-1063 K), as well as zinc selenide (673-1373 K), are investigated using the gravimetric method. Analysis of the experimental data demonstrates that these dependences can be adequately described by equations of the form logP = -A/T + B. The saturated vapor pressures calculated for zinc from the data obtained with the developed gravimetric method are in good agreement with those available in the literature.
