“…The shock compressibility of bismuth has been studied using traditional planar explosive systems [55][56][57][58][59][60][61][62][63][64][65][66][67][68] up to a pressure of 177 GPa. The use of hemispherical explosive systems [69,70] made it possible to obtain a pressure behind the shock wave front in this metal up to 385 GPa [56,61].…”

The purpose of this work is to describe the thermodynamic properties of bismuth in a broad scope of mechanical and thermal effects. A model of the equation of state in a closed form of the functional relationship between pressure, specific volume, and specific internal energy is developed. A new expression is proposed for the internal energy of a zero-temperature isotherm in a wide range of compression ratios, which has asymptotics to the Thomas–Fermi model with corrections. Based on the new model, an equation of state for bismuth in the region of body-centered cubic solid and liquid phases is constructed. The results of calculating the thermodynamic characteristics of these condensed phases with the new EOS are compared with the available experimental data for this metal in waves of shock compression and isentropic expansion. The parameters of shock waves in air obtained earlier by unloading shock-compressed bismuth samples are reconsidered. The newly developed equation of state can be used in modeling various processes in this material at high energy densities.

“…Higher shock-compression pressures in bismuth up to 675 GPa have been achieved using layered cumulative systems and cone-converging shock-wave generators [61]. A high-power laser [67] and a light-gas gun [68] were also used to study phase transformations of bismuth in shock waves.…”
