Abstract
Ionic motion and conduction in (1 − x)PbF2 ⋅ xZrF4 and (1 − x)PbF2 ⋅ xMF (M = alkali-metal cation) solid solutions are studied by 19F and 207Pb NMR and impedance spectroscopy. The factors determining ionic motion in the solid solutions and their structure and energetics in the range 170–550 K are analyzed. The ionic conductivity of (1 − x)PbF2 ⋅ xZrF4 with x ≤ 0.4 and 0.93PbF2 ⋅ 0.07MF is shown to be 10−4 to 10−2 S/cm at temperatures above 425 K, which places these materials among superionics.
