Wide-range equation of state for silver

Abstract

Results of theoretical calculations and experimental measurements of the equation of state (EOS) are discussed and applied to silver. The thermodynamic properties of silver and its phase diagram are calculated with the use of multi-phase EOS model. Theoretical calculations of thermodynamic properties of the solid, liquid, and plasma phases, and of the critical point, are compared with results of experiments. The analysis deals with thermodynamic properties of solid silver at T = 0 and 298 K from different band-structure theories, static compression experiments in diamond anvil cells, and the information obtained in shock-wave experiments. Thermodynamic data in the liquid and plasma states, resulting from traditional thermophysical measurements, "exploding wire" experiments, evaluations of the critical point and measurements of the principal Hugoniot are presented. These data are analyzed in a self-consistent manner.
