Abstract

Nanocrystalline CeO2 powders were synthesized using stearic acid and cerium nitrate by sol-gel and self-propagating combustion coupled method. Influence of various molar ratio of stearic acid and cerium nitrate on the products grain and colour were discussed. Powder appearance, crystal phase, specific grain surface and thermal decomposition process of the products were investigated by XRD, SEM, BET and TG-DSC techniques. Available quantity of stearic acid needed were calculated by the propellant chemistry concepts and thermodynamics equilibrium, and further tested via the experiments. The results indicated that self-propagating combustion powders were composed of CeO2 with small size in 100nm and purity phase of face centered cubic (FCC), and the best burning effect was gained with the stearic acid and cerium nitrate in a 0.25:1 molar proportion.
