| Abstract: | High energy products (BH)max of 365 and 310 kJ·m-3 with intrinsic coercivity iHc of 1640 kA·m-1 of NdFeB sintered magnets were produced. Some new techniques were applied, such as thin NdFeB ingot technique, narrow particle distribution on jet mill, low oxygen content control and high aligned magnetic field press. It is necessary to produce thin NdFeB ingot with fine flake crystal, narrow particle distribution, the average size of NdFeB powders less than 4.0 μm, uniform microstructure, high oriented Nd2Fe14B small grains, and finally high performance NdFeB sintered magnets were prepared. |
