The method for producing MnBi magnet has been studied. A satisfactory high-purity MnBi compound was prepared by sintering powders of Mn and Bi at 260°C for about 1,000 hours. To pulverize MnBi compound,a hammer mill was used in argon atmosphere, and this gave good results. MnBi magnet was produced by pressing powder containing about 8% of resin at 100°C, and curing at 200°C. To obtain good magnetic properties, the magnetic field applied during the pressing should be as powerful as 9,000 Oe or greater. A magnet thus prepared has the residual flux density (Br) of 2,500∼3,800 gauss, and the coercive force (BHC) of 1,200∼2,600 Oe. The thermal coefficient of flux density (α) was about −1.23×10−3 gauss/°C.
