Surfactants Assisted Ball Milling. We herein exploit the advantages of surfactant assisted-high energy ball milling SA-HEBM for the processing of MnAl alloy. In this method, a combination of two surfactants, such as oleic acid and oleylamine, was used along with a solvent, n-heptane, during milling.The use of the SA-HEBM process yielded two ...

2013-4-8 One of the approaches for preparation of magnetic nano-particles is by surfactant-assisted ball milling, a techniqueused for making magnetic fluids.1–3Surfactants aid inachieving smaller particle sizes during milling and dispersingused.4–6the fine particles when appropriate solvents are However, the size distribution of the particles obtained byball milling can be quite wide compared with the chemicalmethods. The chemical methods, nevertheless, have had lim-ited success in the synthesis of hard magnetic nanoparticlesrare-earth compounds.7,8of Traditionally, surfactant-assistedball milling technique has been used mainly for preparingferrite nanoparticles, and not many studies have been con-ducted on the preparation of nanoparticles of different mate-rials, except a few.9,10In this study, systematic efforts havebeen made to prepare and study the properties of the nano-particles prepared by milling soft and hard magnetic materi-als including Fe, Co, FeCo, SmCo, and NdFeB by surfactant-assisted ball milling.
