Influence of Salt Aid on Combustion Synthesis of Nanocrystalline CeO2 Powders

摘要

The present article reports the results of studies related to the synthesis of nano-crystalline ceria powder by combustion process using salt combustion aid.Cerium nitrate as oxidant and urea as fuel were used as reagents,Sodium Chloride was compared as combustion aid.The phase analysis and particle size were compared.The product was characterized by X-ray diffraction,Scanning electron microscopy and Transmission electron microscopy.The results showed that employment ofstarting fuel with combustion aid resulted in synthesizing nano-crystalline ceria powder with fine agglomerates.By using combustion aid,the energetics of the combustion reaction and particle characteristics have been changed.
