Abstract

Abstract

The blasting agentwas prepared by choosing Ce(NO₃)₃·6H₂O as themajor ingredient to synthesize nano-CeO₂ powder by the detonation method.The as-synthesized productswere characterized by X-ray diffraction(XRD)and transmission electron microscopy(TEM).Thereby, the influences of the initiation manners on the crystallization, particle size andmorphology of the as-synthesized productswere analyzed.The results indicate that CeO₂spherical nano-particleswhose crystal structure belongs to cubic system can be synthesized by using the blasting agent in which Ce(NO₃)₃·6H₂O acting as themajor ingredient.And it is an effectivemethod to decrease the particle size and improve the spherification of nano-CeO₂ by increasing the detonation velocity of the blasting agent.
