Structural changes in iron powder during ball milling - ScienceDirectSep 1, 2010 . High purity iron powder (99.99% pure) was milled in a Fritsch P5 Planetary high-energy ball mill using ball to powder ratio of 10:1 at 300 rpm for a period of 0, 4, 8, 12, 16 and 20 h. After every 1/2 h of milling, the mill was stopped for the next 1/2 h to allow for cooling. Toluene was used as a process control.ball mill iron powder,ball mill iron powder,Synthesis of Fe3O4 nanoparticles by wet milling iron powder in a .Fe3O4 nanoparticles with sizes ranging from 30 to 80 nm were synthesized by wet milling iron powders in a planetary ball mill. The phase composition and the morphologies of the as-synthesized products were measured by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy.
