The electrical conductance and transport parameters of pure fused lead + bromide

Abstract

The specific conductance of pure fused lead bromide has been measured in the temperature range 373-810°. The conductance is expressed by (a) a quadratic function of temperature, and (b) a modified Arrhenius function.     Interionic friction coefficients have been evaluated and the applicability of the Nernst-Einstein equation examined.     The variation with temperature of the friction coefficients and of departures from the Nernst-Einstein equation are examined in the light of possible structural models for the fused salt.
