In this study, pure Fe2B nanoparticles were synthesized with a mechanochemical method. The initial
reaction mixture included elemental iron (Fe), boron oxide (B2O3) and elemental magnesium (Mg).
350 rpm rotating speed and 1/40 ball to powder weight ratio were chosen. Fe2B particles were
synthesized after 5 hours grinding. The resulting particles after the reaction were analyzed with X-Ray
diffractometer. The results showed that the powders after ball milling contains mainly Fe2B+MgO
phases. 0.1 M acetic acid was used to remove MgO contamination. The final product in Figure 1
showed pure Fe2B nanoparticles was achieved mechanochemicaly. The reaction equation is given as
Fe + B2O3 + Mg
Fe2B + MgO
