Abstract

Ce-La solid solution were prepared from mixed rare earth chloride via the co-precipitation method using various precipitants: urea, Na2CO3, NaHCO3, (NH4)2CO3 and NH4HCO3. 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. (NH4)2CO3 and NH4HCO3 are confirmed to be more suitable precipitant than Na2CO3 and NaHCO3 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.
