“…The optimization of the thermophysical and thermodynamic parameters of tungsten was performed taking account of the suggestions reported in [8] by using a model that approximates well and reproduces experimental data for lead [9], aluminum [10], and copper [11] in a wide temperature and pressure range.…”

“…The Tait equation was used for the description of the pressure-dependent molar volume of tungsten [12,13]. Unlike the studies [9][10][11], and accounting for the very high melting temperature of tungsten (T m = 3687 ± 7 K [14]), a temperature dependence of the pressure derivative of the isothermal bulk modulus was incorporated into the equation. The final form of the equation is written as:…”

A high-temperature equation of state for tungsten was constructed in this study using experimental data on its thermodynamic properties, thermal expansion, compressibility, and bulk compression modulus. The totality of experimental data were optimized by the temperature-dependent Tait equation over a pressure range from 0 up to 1000 kbar and over a temperature range from 20 K to the melting point. An extended Einstein model was used to describe the temperature dependence of thermodynamic and thermophysical parameters. A linear temperature dependence was embraced for the derivative of the isothermal bulk modulus. The resultant equation of state provides a good fit to the whole set of experimental data within measurement uncertainties associated with individual quantities.
