Abstract : The electrical conductivity of solid ammonium perchlorate was measured over a temperature range from 500K to 600K. From the variation of the ionic conductivity in an applied electric field as a function of temperature, the enthalpy of formation of lattice defects is found to be 24 kcal and the energy barrier for lattice-defect migration, 20 kcal. The relatively high electrical conductivity of ammonium perchlorate compared with alkali halides and the marked influence of gaseous ammonia on the conductivity are interpreted in terms of a mechanism of charge transfer by proton jump.
