Microwave-Based Chemical Synthesis of Co-Alloyed Nd-Fe-B Hard Magnetic Powders

Modern high-energy-product permanent magnets derive their superior properties from nanoscale interactions, which are a sensitive function of the crystal size. Further property improvements require novel synthesis techniques to control the crystal size. Hence, we report a cost-effective and facile technique, i.e., microwave-based synthesis, to produce Co-alloyed Nd-Fe-B-based magnetic nanostructured powder. Dedicated microwave synthesis equipment with an optical pyrometer attachment was used to synthesize mixed metal oxides, followed by reduction diffusion to produce Nd-Fe-Co-B magnetic nanoparticles. Nanosized mixed oxide powders were formed in a single-step combustion after ignition, which was completed within a few seconds. In the reduction diffusion process, a two-step reaction was observed. Co and Fe oxides were first reduced to Fe and Co as the temperature reached <inline-formula><tex-math notation=LaTeX>
