Preparation of CeO_2/Al Nanocomposite Powder by High Energy Ball Milling

Shun‐Lin Li

Abstract

The nanocomposite powder of CeO 2/Al was prepared by high energy ball milling.The variations in microstructure and morphology of the powder during ball milling were investigated by means of XRD,FEM,SEM and EDS.The results show that along with the increase in the milling time,aggregated CeO 2 nanoparticles are embedded in Al particles gradually,dispersed well and distributed uniformly.The crystal size of Al powder is decreased continuously.
