Abstract

The conductivity of the Ba4Ca2Nb2O11 phase and its solid solutions of the formulas Ba4.4Ca1.6Nb2O11 and Ba3.4Ca2.6Nb2O11 is studied as a function of the partial pressure of the water vapor at 2 × 10−2 − 3 × 10−5 atm (log\( P_{H_2 O} \) = −1.7...−4.5) and temperatures of 400–600°C. A model, which is based on the model of structural oxygen vacancies, is proposed for the quasichemical description, providing an adequate explanation of the experimental dependences logσtot= f(log\( P_{H_2 O} \)). It is shown that in the region dominated by the proton transport the log dependences of the conductivity on \( P_{H_2 O} \) have the slope of 1/3. Proton transport numbers are calculated at the given temperatures and pressures of the water vapor.
