Abstract
Ionic conductivity of nominally pure PbF2 crystals, alkali-fluoride-do ped PbF2 crystals (0.5-1 mol % Li, Na, K, or Rb), and the 69 mol % PbF 2 + 31 mol % NaF eutectic composite was measured as a function of temp erature. The introduction of MF causes a sharp rise in sigma and a dec rease in activation energy; the effects of equal concentrations of KF and NaF are virtually identical. The room-temperature conductivity of the eutectic composite is 1.5 x 10(-4) S/cm.
