Structural Features and Electrical Properties of Chlorine-Substituted Proton Conductors Ba4In2+2xZr2−2xO11−x

Аннотация

Chlorine-substituted perovskite Ba_3.95In₂Zr₂O_10.9Cl_0.1 was synthesized for the first time, and its single-phase nature was confirmed by X-ray diffraction method. The resultant perovskite has a cubic structure and is a proton conductor at T < 650°C and p(H₂O) = 2×10⁻² atm. Doping with chlorine was shown to increase the oxygen-ion and proton conductivities.
