چکیده

A statistical-mechanical analytical equation of state has been employed successfully to molten alkaline earth metals. The temperature-dependent parameters of the equation of state have been calculated using our previously reported corresponding-states correlation based on the normal boiling point parameters as the scaling constants. It is shown that knowledge of just normal boiling temperature and the liquid density at a normal boiling point are sufficient to predict the equation of state of magnesium, calcium, stroncium, and barium from the melting points up to several hundred degrees above their boiling points. A comparison of calculated saturated liquid densities of these metals with experimental ones shows that our predicted results are within a 5% difference of experimental ones.
