Pure silver chloride crystals, when cooled rapidly from high temperatures, show enhanced ionic conductivity which may be attributed to quenched‐in Schottky defects. From the annealing out of this extra conductivity one deduces that for an associated vacancy pair the binding energy is 0.42 ev and the migration energy is ≥1.0 ev. The decorability of interior dislocations by swept‐in photoelectrons is also discussed and is shown to be sensitive to the purity of the crystal.
