Abstract
The possibility of analytical determination of the type of electric current conductivity by a solid oxide ion conductor based on stabilized zirconium dioxide (solid electrolyte, superionic) under the influence of a DC electric field and high temperature in the range of 500°-900° degrees is considered. The research objectives of this work are to mathematically interpret the phenomenal phenomenon of substance transfer and irreversible changes in a solid oxide electrolyte (or superionics) of an oxygen concentration cell with mixed electrolyte conductivity. The connection with the need to expand the temperature range of the method and the range of ceramic materials under study is shown. It is confirmed that the sample has a mixed conductivity due to O<sup>2-</sup> anions, Me+ cations and electrons with non-zero concentrations of n<sub>a,k,e</sub>, charges q<sub>a,k,e</sub> and mobility in the field of electric forces. A mathematical formula for determining the mobility of anions and cations in a solid oxide superionic conductor based on stabilized zirconium dioxide is derived.
