Abstract: The high-temperature equation of state (US) of solid lead with a face-centered cubic lattice structure is obtained using
experimental data on thermodynamic properties, thermal expansion, compressibility, and temperature dependence of the volume
compression modulus. The entire volume of experimental data is optimized using a temperature-dependent Void in the pressure
range 0-130 kbar. The temperature dependence of thermodynamic and thermophysical parameters is described using the extended
Einstein model. The obtained US well describes the entire volume of experimental data within the measurement errors of individual
quantities.
