Variation of electrical resistivity with temperature of liquid ternary alloys of Na-K-Rb

Abstract

A model potential and Ziman formulation is employed to study the temperature sensitiveness of electrical resistivity of liquid ternary alloys of Na-K-Rb. The calculated structure factors and form factors are employed for the numerical investigation of electrical resistivity for temperatures in the range 100-500ºC. The binary combinations Na-K, Na-Rb show the Nordheim parabola for increasing temperatures, but there is an exception to K-Rb alloy system. The good agreement for electrical resistivity for pure liquid metals and their binary combination is achieved. The results of electrical resistivity for the ternary combination Na-K-Rb rise with temperatures.
