SPEX high-energy mill using steel balls with a ratio (milling media to powder) of 10:1 (in wt.). The CdS mixtures were mechanically milled during 0, 1, 2, 4 and 8h periods.
In the present study, nano-flake SmCo5 powders with typical flake thickness of 300 nm were prepared by high energy ball milling using valeric acid as a surfactant. In order to remove the surfactant the as-milled powders were heat treated in argon and the effect of the annealing temperature on structural and magnetic properties of the resulting powder was investigated.

Abstract. We performed inelastic neutron scattering measurements on nanophase Fe powders prepared by high-energy ball milling. Neutron energy loss spectra were measured for two states of the material: (1) as milled, when the material had a characteristic nanocrystallite size of 12 nm; and (2) annealed, when the material had a characteristic crystallite size of 28 nm.

Prepared by High Energy Ball Milling The SEM micrographs (Figure 2) show a secondary electron image of powders that were intensively milled in the planetary mill for 5 h. The surface of the powder is irregular due to fracturing during the milling process. This is consistent with the structural analysis by XRD of the 5-h-milled powder.
