Thermoelectric power of ionic conducting crystats

Crystals which conduct electricity by movement of the ions in the crystal have proved rather favorable subjects for the study of lattice defects, vacancies, and foreign ions. In particular, much is now known about their concentrations, their mobilities, and their interactions with one another. With the aim of extending the knowledge, particularly of the kinetic properties of the lattice defects, a study has been made of the electric power of ionic conducting crystals. Previous work on this topic has been almost entirely from the polnt of view of the theory of irreversible thermodynamics. The authors have approached the subject theoretically by making use of the models of Frenkel and Schotlky lattice disorder and have obtained results which are consistent with the thermcdynamic analysis but which allow more detailed predictions to be made.
