Abstract
The paper proposes a chemical model for describing of the thermophysical and transport properties of dense plasmas. In this model, plasma consists of weakly interacting electrons, ions, atoms, molecules and molecular ions, and two- and threefold ionized atoms. Corrections for charge–charge and charge–atom interactions were analyzed. The Debye approximation in the Grand canonical ensemble is used to take into account the charge–charge interaction. We showed that the interaction between charges plays a significant role in the calculation of the plasma properties. The caloric and thermal equations of state and composition of the lead plasma were calculated. The calculation results obtained from the suggested model have demonstrated satisfactory agreement with the experimental data on the equation of state and the electrical resistivity measured recently for a dense plasma of lead.
