Thermodynamic Characterization and Equation of State for Solid and Liquid Lead

A high-temperature equation of state (EoS) for the fcc phase solid lead and liquid was developed herein using experimental data on thermodynamic properties, volumetric thermal expansion, compressibility, temperature-dependent bulk modulus, sound velocity from ultrasonic measurements melting curve. The whole totality optimized Murnaghan EoS over a pressure range 0–130 kbar. temperature dependences thermophysical parameters were described an expanded Einstein model. resultant describes well set available within measurement uncertainties individual parameters.
