Dc and ac electrical conductivity of lead molybdate crystals is studied in the temperature range 300–550 K. The electrical conductivity was shown to have electronic (hole) impurity character. The I – V characteristics are typical of a space charge-limited current. The carrier mobility was estimated to be 10 −5 cm 2 V −1 sat T =300 K. The results of the study suggest the hopping mechanism of conduction in PbMoO 4 crystals.
