Abstract

Abstract

The nano-CeO2 powders were synthesized by detonation using the Ce(NO3)36H2O as the precursor. The detonation products were characterized by XRD and TEM.Influences of urea and NaNO2 in explosive on the morphology of detonation products were investigated. The three experimental results indicate that the obtained CeO2 crystals are cubic fluorite structure and their granule dimensions are 45, 64, 33 nm, respectively. The powders are spherical when urea is added and the sizes of the powders are small when Na(NO3)36H2O is added in the explosive.
