We report an approach to improve the electric resistivity of Nd-Fe-B die-upset magnets without sacrificing their magnetic properties very much. NdF3 fine powders were segmentally added in the die filling with MQU-F powders and then were die-upset for magnets. Experimental results indicated that electric resistivity monotonically increases with the increase of NdF3 addition, which is due to the formation of continuous segmented fluoride layers. When NdF3 content reached 5.3 wt%, the electric resistivity almost increases by eight times. Magnetic properties exhibit no drastic decrease after the addition of NdF3 and coercivity increases when adding 2.12 wt% of NdF3.
