Abstract

A systemic investigation was done on the chemistry and crystal structure of boundary phases in sintered Ce9Nd21FebalB1 wt magnets Ce2Fe14B is believed to be more soluble in the rareearth RErich liquid phase during the sintering process Thus the grain size and oxygen content were controlled via lowtemperature sintering resulting in high coercivity and maximum energy products In addition Ce formed massive agglomerations at the triplepoint junctions as confirmed by elemental mapping results Transmission electron microscopy TEM images indicated the presence of CeNdO x phases at grain boundaries By controlling the composition and optimizing the preparation process we successfully obtained Ce9Nd21FebalB1 sintered magnets the prepared magnets exhibited a residual induction coercivity and energy product of 1353 T 759 kA/m and 342 kJ/m3 respectively
