摘要: In the die-pressing method of the magnet powder and fine powder, the powder is filled at a high density in a rubber mold (10), is occasionally preliminarily magnetized (4a) in the rubber mold and is then compacted under magnetic field or without magnetic field. Cracking of the magnet green compact is prevented. A sintered compact having density of 90% or more can be produced using the fine powder.
