%X magnetic spheres were produced by adaptating conventional ar-he thermal spray processes. this process is based on the projection of different iron oxides-rich powder precursors which are common byproducts of diverse metallurgical industrial activities. projected particles are trapped inside a special capturing device. prior to the plasma processing, precursor materials were milled in order to homogenize their initial particle sizes. the produced magnetic particles showed a spherical morphology with different superficial structures. their composition includes a mixture of crystalline phases that could be indexed to the magnetite (fe3o4), maghemite (gamma-fe3o4) and other phases depending on chemical composition of used precursor. complete characterization of magnetic spheres was achieved by using several analysis techniques such as: x-ray diffraction (xrd), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), x-ray energy dispersive spectroscopy (eds) and vibrational sample magnetometry (vsm).
