• W1984181803 abstract "In this paper, we report the synthesis, chemical stability and electrical properties of three new Ta-substituted double perovskite-type Ba2Ca2/3Nb4/3O6 (BCN). The powder X-ray diffraction (PXRD) confirms the formation of double perovskite-like structure Ba2(Ca0.75Nb0.59Ta0.66)O6−δ, Ba2(Ca0.75Nb0.66Ta0.59)O6−δ and Ba2(Ca0.79Nb0.66Ta0.55)O6−δ. The PXRD of CO2 treated (800 °C; 7 days) and water boiled (7 days) samples remain the same as the as-prepared samples, suggesting a long-term structural stability against the chemical reaction. The electrical conductivity of the investigated perovskites was found to vary in different atmospheres (air, dry N2, wet N2, H2 and D2O + N2). The AC impedance investigations show bulk, grain-boundary and electrode contributions in the frequency range of 0.01 Hz to 7 MHz. Below 600 °C, the bulk conductivity in wet H2 and wet N2 was higher than in air, dry H2 and dry N2. However, an opposite trend was observed at high temperatures, which may be ascribed to p-type electronic conduction. The electrical conductivity of the investigated perovskites was decreased in D2O + N2 compared to that of H2O + N2 atmosphere. This clearly shows that the investigated Ta-doped BCN compounds exhibit proton conduction in wet atmosphere which was found to be consistent with water uptake. The water uptake was further confirmed by thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) characterization. Among the samples investigated, Ba2(Ca0.79Nb0.66Ta0.55)O6−δ shows the highest proton conductivity of 4.8 × 10−4 S cm−1 (at 1 MHz) at 400 °C in wet (3% H2O) N2 or H2, which is about an order of magnitude higher than the recently reported 1% Ca-doped LaNbO4 at the same atmosphere and at 10 kHz." @default.
