With the increasing of the sintered NdFeB magnet application, there is a great deal of the demand of Nd, consequently the price of Nd is rising. Therefore, it is necessary to produce a novel sintered NdFeB magnet at low costs. In this paper, the dual-main-phase CeNdFeB magnets were prepared. The corrosion potential of Ce is −2.48V, which is lower than that of Nd (−2.41V) [1]. But Ce is much cheaper...
