CHEMICAL STABILITY AGAINST CO2 OF HIGH PROTON CONDUCTOR YTTRIUM DOPED BARIUM CERATE

摘要：

Single phase BaCe1.xYxO3δ(0≤X≤0.25) was successfully prepared via Pechini method. X-ray diffraction revealed that BaCe1.xYxO3-δ(0≤X≤0.1) was single phase of orthorhombic structure and specimen (0.15≤X≤0.25) was single phase of monoclinic structure at room temperature. From TG measurements in CO2 flow, the apparent rate constant of the CO2 decomposition of BaCe1-xYxO-3δwas estimated. The apparent rate constant enhancement with increasing Y content could be ascribed not to increase of activation energy but to frequency factor of the decomposition reaction.
