The 20 % yttrium doped barium cerate (BCY20) powder has been synthesized by cost effective solution combustion method. The flame temperature measured by pyrometer was 1055°C, less than the adiabatic temperature due to various losses. The phase formation and evolution was studied with TG-DTA and XRD. The carbonate free orthorhombic BCY20 phase was obtained upon calcination at 900°C. The microstructure of the powders and sintered pellet was examined through scanning electron microscopy. The vibrational mode at 355 cm, characteristics of CeO 6 octahedra, was detected in Raman while the bands corresponding to M-O vibrations were revealed in FT-IR. The dc conductivities of sintered pellet measured in argon and air atmospheres at 600°C were 1.53×10 −3 and 1.41×10 −3 S/cm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
