Equation of State for Alkaline Earth Metals: Prediction from Surface Tension

The knowledge of thermodynamic properties of liquid metals is of considerable interest in industry. Liquid metals have a number of interesting characteristic, which make them applicable in high- temperature operations as heat transfer agent and reactor coolant. The most important characteristics of them are high boiling points, extended liquid range, high thermal conductivities, low vapor pressure, and high heat of vaporization. The present work is concerned with modifying the original Tao-Mason EOS [۱] to calculate the temperature-dependent parameters of the equation of state for molten alkaline earth metals (Mg through Ba). It is shown that this procedure leads to an analytical equation of state which can predict the saturated liquid density of these metals from the melting point up to several hundred Kelvin above the boiling point within ۰.۶۵۴%. In the next section, we shall introduce the EOS in question
