Da Cunha et al. [5] used wet high-energy ball milling for preparations of Cr 3 C 2-25(Ni20Cr) powders.They used liquid hexane as milling control agent to reduce the average particle size. In addition, they milled the powders under nitrogen gas atmosphere and found that this led to the formation of uniform nanoscale powders with an average particle size of 11 mm in diameter.

In this study, cobalt ferrite (CoFe2O4) nanoparticles were synthesized by intensive mechanical alloying of CoCO3 and α-Fe2O3 powder using a planetary high energy ball mill in air without any subsequent heat treatment. Effects of milling time on the phase composition, morphology and magnetic properties of the powders were evaluated using XRD, FESEM and VSM techniques, respectively.
