RCsumC. - Quand on ajoute aux metaux alcalins liquides des ions halogenes, on deplace de la bande de conduction des electrons jusqu'a ce qu'on forme un sel isolant. Quand on a remplace a peu pres 30 % des ions metalliques par des ions halogenes, on depasse la limite Landau au-dela de laquelle l'equation de Boltzmann la plus simple ne s'applique plus.

Nous avons employe une approximation, celle du cr potentiel coherent n, pour construire une equation de transport auto-coherente, et nous avons calcult la resistivite tlectrique des solutions de K-KC1.

Abstract. - As halide ions are added to liquid alkali metals electrons are removed from the conduction band until the insulating salt is formed. When something like 30

%

of the alkali metal ions are replaced by halide ions the Landau limit for the applicability of the simplest Boltzmann equation is violated.

A coherent potential approximation has been used to construct a self consistent transport equation and calculations have been made of the electrical resistivity of K-KC1 solutions.
