Ball milling: The main principle of mechanical milling can be described as the exploitation of high energy grinding to reduce the particle size. In general, the high energy ball milling route is used to yield nanosized particles, especially for metallic PNPs synthesis [45]. To initiate the size reduction process, bulk samples of the NPs are ...

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.
