The defect parameters in β-PbF2 that were determined from the association and extrinsic regions of the isobaric conductivity plot, as well as from conductivity measurements under various pressures, were studied. It was found that, in the low-temperature range where bulk elastic and expansivity data were available, the defect volumes scaled linearly with the defect enthalpies with a slope which was governed by bulk qualities. A deviation from linearity was observed in the high temperature range from which the relevant parameters for the anion Frenkel formation process were deduced.
