Partial conductivities in perovskites CaZr1–xScxO3–α (x = 0.03–0.20) in an oxidation atmosphere

Resumo

Partial (ionic, proton, and hole) conductivities of oxides CaZr_1–xSc_xO_3–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 \({P_{{H_2}O}}\)= 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.
