Abstract

A wide-range semiempirical equation of state for aluminum applicable both at near-normal conditions and in dense plasma is presented. The finite-temperature Thomas–Fermi model is used for the thermal contribution of electrons thus diminishing the number of fitting parameters and giving information about a mean ion charge. The constructed equation of state agrees with majority of available shock-wave data (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
