Fe50Co50 nanoparticles via self-propagating high-temperature synthesis during milling

Self-propagating exothermic reactions during mechanical milling of FeCl3/CoCl2 mixture together with sodium seeds resulted in formation of Fe50Co50 nanoparticles. Highly exothermic reactions resulted in temperature raise and formation of Fe50Co50 phase within the first 5 min; however Fe50Co50 single-phase was obtained after 30 min of milling. The products were characterized by XRD, SEM, EDS, TEM and VSM. Obtained results showed that both milling time and NaCl salt matrix affected the size, morphology, microstructure and magnetic properties of the produced particles.
