Abstract: The equilibrium vapor pressure of antimony triiodide (SbI3) has been measured over a temperature range from â??20 to 47 °C using a classical Knudsen cell method. An analysis of the slope of that data as a function of temperature yields an enthalpy of sublimation (ΔHvapor) value of ΔHvapor = –128.48 kJ/mol for SbI3.
