Title: Thermodynamic and Transport Properties of Beryllium Vapor in the Supercritical Fluid State

Abstract

The thermal and caloric equations of state, composition, and conductivity of a supercritical beryllium vapor are calculated using the earlier proposed “3+” chemical model, which incorporates atoms, electrons, ions, and electron jellium with allowance for interatomic and intercharge interactions. The introduction of an electron jellium makes it possible to describe the pressure-induced ionization and explain the increase in the conductivity of beryllium vapor under compression. The cohesive bond of atoms caused by the electron jellium compensates for interactions when calculating the composition and reduces the effect of intercharge interactions on the equation of state. The parameters of the beryllium critical point and the applicability domain of the model are discussed.
