Abstract. Ce-La solid solution were prepared from mixed rare earth chloride via the co-precipitation method using various precipitants: urea, Na 2 CO 3 , NaHCO 3 , (NH 4 ) 2 CO 3 and NH 4 HCO 3 . The effects of the precipitants on the physicochemical properties, crystal structure and morphology of the Ce-La solid solution are investigated. The CL-urea sample displayed the largest surface area and the most uniform morphology. (NH 4 ) 2 CO 3 and NH 4 HCO 3 are confirmed to be more suitable precipitant than Na 2 CO 3 and NaHCO 3 for Ce-La solid solution preparation, because of the higher surface and less impurity residue of the corresponding samples. The effect of reverse method duing precipitation on Ce-La solid solution properties was not significant when the precipitant was excessive.
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.
