This paper is devoted to a systematic investigation of linear transpor
t properties in strongly coupled binary ionic mixtures of pointlike io
ns interacting solely through Coulomb interactions. The basic formalis
m rests upon suitable extensions of the Boltzmann-Ziman equation. Calc
ulations are performed within binary ionic mixture (BIM) and polarized
BIM (PBIM) frameworks respectively. We emphasize out the electron ele
ctric resistivity behavior investigated in the vicinity of critical io
n demixing.
