The electrical conductivities of translucent BaZr0.5Ce0.3Y0.2O3-δ (x=0.5, BZCY532), BaZr0.6Ce0.2Y0.2O3-δ (x=0.6, BZCY622) and BaZr0.7Ce0.1Y0.2O3-δ (x=0.7, BZCY712) proton conductors were investigated systematically in different atmospheres and also at different oxygen partial pressures. The obtained results indicate that translucent BZCY532, BZCY622 and BZCY712 ceramics are pure oxygen-ion and proton...
Dense and translucent BaZrxCe0.8−xY0.2O3−δ (x=0.5, 0.6, 0.7) proton conductors were firstly and successfully prepared by Spark Plasma Sintering (SPS) at a temperature of 1350°C without sintering aids’ addition. XRD, SEM and EDS were applied to determine the phase purity, morphology and element composition of prepared pellets, respectively. Moreover, the sintering behaviors of these proton conductors...
