Prediction of the density of molten metals

A corresponding-states correlation for the prediction of the liquid density of alkali metals has been employed to calculate the liquid density of a wide variety of liquid metals including alkaline earth metals, gallium, indium, thallium, tin, lead, antimony, bismuth, and a number of transition metals. The correlation requires the values of the melting and boiling point parameters of metals plus an adjustable parameter, used to predict the saturated liquid densities. We have calculated the liquid density of above mentioned metals over a wide temperature-range from undercooled temperatures up to several hundred degrees above the boiling point and at pressures from vapor pressure up to 200 MPa, where the experimental data are reported in the literature. From 277 data points examined for the afore cited liquid metals the average absolute deviation is 0.386%.
