X-ray diffraction (XRD), scanning electron microscopy (SEM), inductive-coupled plasma spectroscopy (ICP), oxygen analyzer were used to investigate the solid state reaction of Nd2Fe14B powders with carbon. The experiment results revealed that Nd-rich phase (FCC-NdO) was formed after sintering when the samples contain oxygen (1 percent). With the carbon content of Nd-rich phase increasing, the Nd-rich phase changed from FCC-NdO phase to h-Nd2O3 phase. And the phase evolution of Nd-rich phase was sensitive to the carbon concentration as well as the sintering time. When the oxygen free samples sintering over 1100 ℃, the phase evolution of iron was sensitive to the sintering temperature. With the temperature increased to 1300 ℃, the Nd-rich compounds (NdFeC compounds) decreased and the NdC2 increased.
