  • In order to synthesize nano-ceria by detonation method, 5 kinds of emulsion explosives in which Ce(NO3)3·6H2O acted as main oxidant were designed and prepared.Considering the effects of the content of Ce(NO3)3 on the detonation velocity of emulsion explosives and the yield of nano-ceria, the formulas of emulsion explosives for preparing nano-ceria were screened.Nano-ceria was synthesized by initiating the emulsion explosive in explosion vessel.The as-synthesized products were characterized by XRD and TEM.The result from XRD test indicates that the nano-ceria belongs to cubic phase.The mean size of ceria grain is 74 nm based on the calculation result according to Scherrer equation.The result from TEM test presents that the as-synthesized ceria particles are spherical by appearance, they have well dispersion and the size was uniform.According to TEM test result, the mean diameter of ceria particles is about 70 nm, which coincides with the calculation result perfectly.
