摘要：

The total conductivity of CaZr1 - x Sc (x) O3 - alpha (x = 0.01-0.20) materials has been measured by the four-probe dc method at temperatures from 600 to 900A degrees C in humid air (pH(2)O = 40-2500 Pa), and CaZr0.95Sc0.05O3 - alpha has been characterized by impedance measurements. The ion and proton transport numbers in CaZr0.95Sc0.05O3 - alpha have been determined as functions of air humidity. The observed anomalies in the temperature dependences of electrical conductivity for the materials studied have been compared to dilatometry data and interpreted in terms of structural changes in their oxygen sublattice.
