摘　　要：The study of electrical resistivity of simple binary liquid alloy Na-K is presented as a function of concentration. Hard sphere diameters of sodium （Na） and potassium （K） are obtained through the inter ionic pair potentials evaluated using Troullier and Martins ab-initio pseudopotentials, which have been used to calculate partial structure factors S（q）. Tile Ziman formula for calculating resistivity of binary liquid alloys has been used. Form factors are calculated using ab-initio pseudopotentials. Tile results suggest that the first principle approach for calculating pseudopotentials with in the frame work of Ziman formalism is quite successful in explaining the electrical resistivity data of compound forming binary liquid alloys.The study of electrical resistivity of simple binary liquid alloy Na-K is presented as a function of concentration.
