PURPOSE: To enhance the magnetic characteristics by a method wherein a material mixture with a material fine particles for rare earth element sintered magnet is manufactured using a solvent such as mineral oil, synthetic oil, plant oil, etc., to be wet-molded for manufacturing a rare earth element sintered magnet body by dissolvent sintering steps. CONSTITUTION: Within the manufacturing method of rare earth element permanent magnet comprising R-Co5 base, R2 Co17 base, R-Fe-B base (R represents one kind or two or more kinds of rare earth elements including Y) is wet-fine crushed in a solvent such as mineral oil, synthetic oil, plant oil, etc., to manufacture a material mixture comprising a solvent and fine particles, next this material mixture is wet-molded in a magnetic field into a molded body later a sintered body by dissolvent and sintering steps. Through these procedures, the title rare earth element permanent magnet sintered body containing a small quantity of oxygen, nitrogen, carbon can be manufactured, thereby enabling the high magnetic characteristics to be displayed. |
