Abstract: The extended Ziman formula is employed to calculate electron conductive opacities of hot dense plasma. All required parameters in the formula are calculated by using relativistic self – consistent ion –sphere model. The degenerate effect is described by the Fermi –Dirac distribution. A parametric structure factor is used to consider the effect of ionic structure. The differential cross section for the elastic scattering of electrons is computed by the partial –wave expansion method. The results are compared with experimental and other available theoretical values.
