In this work, a facile co-precipitation route was adopted to synthesis ceria particles. Cerium nitrate hexahydrate and sodium carbonate were used as the precursors. Study of the effect of pH and calcination temperature on synthesized ceria particles were carried out in detail. The surface morphology was found to be influenced significantly by change in solution pH, as evinced from SEM results. XRD spectra revealed improvement in crystallite size for synthesized nanoceria calcined at different temperatures
