Abstract:
Partial (ionic, proton, and hole) conductivities of oxides CaZr1−xScxO3−α (x = 0.03–0.20) with the perovskite structure in air atmosphere have been studied as functions of temperature in the range of 600–900∘C and partial water-vapor pressure in the range of pH2O = 40–2500 Pa. The influence of the humidity of the atmosphere on the relative change in the concentration of oxygen vacancies as a function of temperature has been estimated.
Keywords:
Perovskite, Oxygen Vacancy, Transport Number, Hole Conductivity, Partial Conductivity.
