METHOD FOR MANUFACTURE OF POWDER TEXTURED MAGNET Russian patent published in 1994 - IPC

Abstract RU 2015857 C1

FIELD: manufacture of powder textured magnet. SUBSTANCE: alloy of rare-earth metals with 3d-metal is melted, and crushed and ground to obtain suspension in ethyl alcohol, with powder-to-alcohol ratio of 1:3. Suspension is subjected to ultrasonic dispersion with frequency of 19-25 Hz with simultaneous superimposing of orienting magnetic field for 15-30 s. Powder is pressed with pressure of 0.5-2.0 t/sq.cm in magnetic field with intensity of 15-20 kOe. EFFECT: higher efficiency. 1 tbl
