Theoretical prediction of melting curves of gold and silver up to pressure 150 GPa

Change in the melting temperature of metals with an increase in pressure

“…It should be noted that dependence T m (P) for FCC-Au was also calculated by various analytical methods in [9,[32][33][34], where good agreement with the experimental data was achieved (see Table 1). However, in [9,32] for transformation of volumetric dependences into baric dependences, various phenomenological equations were used.…”

“…In [32], for this purpose, the Vinet equation of state and relation γ = γ 0 (V /V 0 ) q , where q = 1 was postulated for the second Gruneisen parameter. In [33,34], calculations were carried out using the statistical moments method, SMM. SMM from [33,34] is also based on the Mie−Lennard-Jones pair interatomic interaction potential (8).…”

“…In [33,34], calculations were carried out using the statistical moments method, SMM. SMM from [33,34] is also based on the Mie−Lennard-Jones pair interatomic interaction potential (8). However, SMM is much more sophisticated that our method from (8)− (17).…”

“…In [33], for transformation of volumetric dependences to baric dependences, power approximation of the equation of state of gold obtained at T = 0 K was used. In [34], dependences P(V, T ) for Au were not presented. Therefore, the issue of correct pressure calculation by the method used in [34] remains open.…”
