Abstract

In this paper we report an extensive neutron diffraction investigation at high temperature on the BaCe0.80Y0.20O2.9 proton conducting material. Our results precisely define the structural evolution of the compound as a function of temperature which is from a monoclinic (room temperature) to a cubic (800C) structure. Neutron data have been correlated to calorimetric measurements (TGA and DSC) and conductivity properties of the material.
