Abstract. An analytical equation of state, originally derived for normal fluids, is applied to
predict the liquid density of saturated molten alkaline earth metals. Three temperature-dependent
parameters of the equation of state are calculated as functions of reduced temperature with the
use of the law of corresponding states. The results show that the saturated liquid densities of
magnesium, calcium, strontium, and barium can be predicted from the melting point up to
several hundred degrees above the boiling point. In particular, it is shown that two easily measurable constantsöthe latent heat of vaporisation and the liquid density at the boiling pointöare
sufficient to determine the P^V^T properties for these metals within an accuracy of 5%.
