Abstract
PURPOSE: To readily produce the permanent magnet of superior strength and magnetic performance by kneading thermosetting organic resins as a binder to magnetic powder composed of the intermetallic compound of rare earth metals and Co and press molding the mixture.
CONSTITUTION: Rare earth metals such as Sm, Y, Ce, La, Pr, mischmetal, etc. and Co are melted in a high frequency furnace in Ar atmosphere, whereby the intermetallic compound of rare earth metals and Co is produced. After cooling and freezing, it is ground to sizes of 5 to 20μ. Thermosetting organic resins of 100 to 20000 cp in viscosity are added at 4 to 6% as a binder to this powder and the mixture is kneaded. The mixture is press molded with a magnetic field press and the molding is heated to 150°C to solidify. The permanent magnet which is free from any flaws, is highly strong and has stable magnetic performance is obtained.
