    Abstract:

    Vapour pressure is a sensitive method for thermodynamic characterization of molten salts due to proportionality between activity and pressure. The method has also validity over a large temperature range as Log P is proportional with 1/T. Pressure can be measured in the range 1 to 60 Pa by use of the following methods:Knudsen effusion, transition flow, static, transpiration or boiling point.Determination of vapour pressure of Cloroaluminates melts and NaF-Al2O3-SiO2 slags are given as examples. Solubility of gas in molten salt is also discussed.
