We present the process of synthesis and characterization of magnetite-maghemite nanoparticles by the ball milling method. The particles were synthesized in a planetary ball mill equipped with vials and balls of tempered steel, employing dry and wet conditions. For dry milling, we employed microstructured analytical-grade hematite (α …

Synthesis Of Nano Particles Ball Milling Method. Nano-sied Ba x Mg 1x Fe 2 O 4 ferrite particles less than about 150 nm were prepared by Y. Choi et al73 by using self-propagating high temperature synthesis and mechanical ball milling. It was observed that as the ratio of BaO 2 to MgO in the initial powder composition varied from 0.25 to 4.

High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the literature for the synthesis of intermetallic nanoparticles. Before a mechanical milling is started, powder (s) is loaded together with several heavy balls (steel or tungsten carbide) in a container.

The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher …
