The variations of the conductivity of solid-state materials as a function of the temperature and the ambient atmosphere are often explained on the basis of structural or chemical modifications. When electrical and structural studies are performed separately, reliable correlations are not easy to establish. It is particularly true when the phase transition depends on the thermal protocol. Such an example is provided by BaCeO<sub>3</sub> for which two structural changes were evidenced by Raman spectroscopy. The temperature for the orthorhombic-tetragonal modification was particularly difficult to define.
