A new regularity and an equation of state for alkali metals over the whole liquid range

A new equation of state for molten alkali metal alloys

“…According to our previous study [15], the semi empirical (6-3) potential function, on which the asymptotic behavior of both attractive and repulsive parts has been accounted over the whole liquid range, is proper for different liquid alkali metals. The form of this pair potential function is as follows:…”

“…(1) describes the effective pair potential of liquid alkali metals fairly well [15], this potential has been used in this work. The parameter D(T) in Eq.…”

“…In this work, a new equation of state (EoS) reported originally for pure liquid alkali metals [15] has been extended to predict the density and other thermodynamic properties such as isobaric expansion coefficient, α P , isothermal compressibility, κ T , and internal pressure, P i , of binary molten alloys of Na-K and Cs-K from the freezing point up to several hundred degrees above the boiling point using quadratic mixing rules along with the mean geometry approximation (MGA). A wide comparison between the densities predicted using this work and those of some previous works has been made.…”

Density prediction of liquid alkali metals and their mixtures using an artificial neural network method over the whole liquid range

“…During the last decades, many studies have been devoted to prediction of thermodynamic properties of liquid alkali metals [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], and their alloys [25][26][27][28][29]. Different authors used different equations and methods to predict and reproduce the thermodynamic properties of these systems.…”
