Abstract: On the basis of a relativistic self-consistent temperature and density-dependent Hartree-Slater "average atom" model, the error of electron conductive opacities by approximating the self-consistent electron-ion potential with two superimposed Yukawa potentials was checked. The electron conductive opacities for titanium are given by the direct numerical integral at temperatures ranging from 10eV to 10³eV and for densities from 0.1 p₀ to 10/7n(p₀ = 3.988g/cm³).
