Tsai, “Effect of lithium fluoride on thermal stability of proton-conducting Ba(Zr0.8-xCexY0.2)O2.9 ceramics,” Solid State Ionics 181, 1654-1658 (2010). doi: 10.1016/j.ssi.2010.09.052.0167-2738https://scholarworks.montana.edu/handle/1/15221In-situ X-ray diffraction (XRD) and micro-Raman scattering have been used to study the thermal stability of lithium fluoride (LiF)-added (7% weight ratio) Ba(Zr0.8−xCexY0.2)O2.9 (BZCY: x = 0.1 and 0.2) proton-conducting ceramic powders as a function of temperature in 1 atm of flowing CO2. This work reveals that LiF-addition can reduce the thermal stability of Ba(Zr0.8−xCexY0.2)O2.9 in CO2 and cause decomposition to BaCO3, and possibly Ba3Ce2(CO3)5F2 (or CeCO3F), and Y2O3-like compound after exposure to CO2 from high temperatures. LiF-related compounds can be removed after calcining (or sintering) in air above 1200 °C, but a minor amount of a Y2O3-like compound could remain after calcining at 1400 °C in air.enThis Item is protected by copyright and/or related rights.
