Abstract
Nanostructured ceria particles have been successfully synthesized by detonation
method with emulsion explosives. The effects of mass content of
Ce(NO3)3·6H2O in emulsion explosives on particle size of CeO2 were
investigated. X-ray diffraction (XRD) and Transmission Electron Microscope
(TEM) were carried out to characterize as-synthesized powders. The ultraviolet
absorption performance of nanostructured ceria was tested by ultraviolet
spectrophotometer. The results indicated that the mass content of
Ce(NO3)3·6H2O in emulsion explosives affected the particle size of ceria mostly.
When the mass content of Ce(NO3)3·6H2O was 53.2%, the particle size of ceria
was even and on the small side. The UV absorption performance of assynthesized
nanostructured ceria was excellent, especially for ultraviolet B.
Keywords: nanostructured ceria, detonation synthesis, UV absorption, emulsion
