PURPOSE:To obtain a bond magnet which has high saturation magnetization and residual magnetic flux density by mixing an organic compound made of only carbon and hydrogen with rare earth magnet powder, by treating the mixture for aging after it is formed in a magnetic field and then by curing and solidifying it by impregnating it with a bond agent. CONSTITUTION:A liquid state or fine powder state organic compound made of only carbon and hydrogen of weight of 6 weight % or less of magnet powder is mixed as a forming assistant with the 2-17 system rare earth magnet powder of coercive force 6 kOe or less before an aging treatment. After the mixture is formed in a magnetic field, the obtained compact is subjected to aging. The treated compact is impregnated with a bonding agent and is cured. Then, the friction among the magnet powder is reduced, the orientation is improved and the magnet powder is densely packed. This enables obtaining a bond magnet which has high saturation magnetization and residual magnetic flux density. |
