The composition of metal plasmas provides the fundamental parameters for the thermodynamic, optical, and transport properties research. In this paper, the composition of the plasmas, considering the threefold ionization of metal, the polarization between neutral particles and electron, and the Coulomb interactions among the charge particles, (including ion-ion, electron-ion, and electron-electron interactions), is calculated by partially ionized plasma model. Furthermore, the electrical conductivities of titanium and silver are calculated by using linear response theory. The reliability of the model is verified by comparing with available experimental data. Furthermore, the thermal conductivities and thermopower of titanium and silver in the range of 0.001—2.0 g/cm3, 1.5×104—2.5×104 K are predicted, which provides the reference for the experiment of transport properties of metal plasmas.
