It was noted that a high conductivity could be imparted to β-PbF2 by introducing trivalent ions which created an excess concentration of fluoride ions. Experimental data on the ionic conductivity of Pb1–xMxF2+x (M = In, Sb or Bi), were presented here. Limited information concerning the high ionic conductivity of doped Pb1–xAlxF2+x–2yOy had been reported. Here, the ionic conduction at 272 to 473K of pure Pb1–xAlxF2+x–2yOy, and of samples doped with fluorides of transition metals (Zn, Cu, Ni, Co, Mn, Cr, V, Ti), was studied in greater detail.
