Abstract. We have synthesized pure nanocrystalline CeO 2 powders of nearly spherical shape using highenergy attritor ball mill. Milling parameters such as the milling speed of 400 rpm, ball to powder ratio (40:1), milling time (30 h) and water cooled media were determined to be suitable for synthesizing nanosize (∼10 nm) powders of CeO.
