Partial conductivities in perovskites CaZr1-x Sc x O3-α (x=0.03-0.20) in an oxidation atmosphere

Partial (ionic, proton, and hole) conductivities of oxides CaZr1-x Sc (x) O3-alpha(x = 0.03-0.20) with the perovskite structure in air atmosphere have been studied as functions of temperature in the range of 600-900A degrees C and partial water-vapor pressure in the range of = 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.
