Partial resistivity analysis of the NaK, NaRb and NaCs liquid alloys

The total resistivity for the NaK, NaRb and NaCs alkali alloys was divided into partial resistivities and calculated by means of Zimans's formula within a simplified and semi-empirical approach. It is shown that the height of the parabolic resistivity behavior versus concentration is related to the scattering potential whereas the position of the maximum depends on the structure of liquid. Further it appears clearly that the leading contribution is due to the sodium as a result of its muffin tin zero enhancement with respect to its value in the pure liquid phase.
