Structure specific features and ionic transfer in superionic conductors with mixed ionic-electron conduction

Binary, ternary and quarter chaleohenides of cooper and silver, possessing the mixed ion-electron conduction and displaying the abnormal high conduction on cooper and silver cations are considered in the paper aiming at the investigation of structural features and effects of the ionic transfer in mixed ionic-electron conductors with the high cation conduction. The establishment of the connection between the compound, structure and parameters of the ionic transfer and the development of model representations about processes of the quick ionic transfer are also the aim of the paper. As a result the connection between structural characteristics and parameters of the ionic transfer has been established, model representations about processes of the quick ionic transfer have been developed. The description of physical processes, proceeding in systems with the mixed conduction, has been given in frameworks of the phenomenological and statistical approaches. Parameters, characterizing the ionic transfer in superionic materials with the mixed conduction, which have the inquiry character and may be used in the calculation of technological parameters of the similar material synthesis and in the design of devices, including the mixed conductor as composite elements, have been obtained. Superionic conductors with the mixed ionic-electron conduction may be used as electrode materials for current sources and also as components of solid-body ionic devicesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
