BaCeO3: Materials development, properties and application
Medvedev, D.; Murashkina, A.; Pikalova, E.; Demin, A.; Podias, A.; Tsiakaras, P. (2014)The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ... -
Conductivity of Gd-doped BaCeO3 protonic conductor in H2-H2O-O2 atmospheres
Medvedev, D.; Murashkina, A.; Demin, A.; Tzorbatzoglou, F.; Tsiakaras, P. (2013)This work proposes a radically new simple method of evaluation of the proton conductivity based on measurement of the conductivity of ceramic materials depending on the oxygen partial pressure (pO2) at a gradual transition ... -
