Some scrap Nd-Fe-B magnets were added in the preparation of sintered Nd-Fe-B,and feed of Nd,Fe,B raw materials were accordingly reduced to prepare the samples by forming,sintering and subsequent processing.Powder size,microstructure and magnetic properties were tested and comparative analysis was done on the Nd-Fe-B samples with and without scrap magnets.The results show that the particle size concentration of the sample with scrap magnets is slightly lower than that of the sample without scrap magnets,and a small portion of particles in the former are of the size over 100μm.However,the two samples have basically consistent microstructure,their magnetic flux decreases together with the increase of aging temperature,and they also have the same thermal variation law.
