Abstract

In this paper the role of the preparation route on the sintering temperature, microstructure and transport properties of BaCe~0.8~Y~0.1~Zr~0.1~O~3‐δ~ solid solution has been studied. In particular, the samples were synthesized by means of the solid‐state and molten salt synthesis method. The sample properties were investigated by means of X‐ray diffraction, scanning electron microscopy and impedance spectroscopy. It was found that a good sintering of the samples could be achieved at 1500 °C for MSS preparation method. The ceramic route, even at higher temperatures, does not lead to better conductivity.
