摘要：

Within a phenomenon-based model of dynamic conductivity of superionic conductors, the contribution of Li+-ionic conductivity to forming the frequency dispersion of non-stoichiometric ceramics Li2O-Fe2O3Al2O3 at various temperatures has been investigated. There have been determined the predominance of electronic type of conductivity at temperature rate of 295-450 K realised by percolation mechanism. With further temperature rising Li+-cationic conductivity is becoming predominant. With Al( )(+3)ionic content rising in the patterns Li+-tionics conductivity is increasing, but their mobility is decreasing at all temperature rates within the investigation. (C) 2019 Elsevier Ltd.
