Abstract
The semiempirical expression of the free energy of lithium deuteride in the form of an analytical function of volume and temperature for the pressure range of 0–100 GPa and at 200–2000 K was developed. The thermodynamic description was based on experimental data of thermophysical properties at normal conditions and lithium deuteride Hugoniot. The predictive calculations of a set of thermophysical properties of lithium deuteride at high pressures (including shock conditions) and temperatures were performed. A comparison of isotherms, isobars, heat capacity, and thermal conductivity with literature experimental data was presented. The results made it possible to consider, compare, and coordinate the data on the shock and isothermal compression of lithium deuteride at high pressures and temperatures from a unified point of view.
