摘要：
In this paper the role of the preparation route on the sintering temperature, microstructure and transport properties of BaCe0.8Y0.1Zr0.1O3-delta 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 degrees C for MSS preparation method. The ceramic route, even at higher temperatures, does not lead to better conductivity.
