Abstract

PURPOSE: To obtain an Mn-Al-C magnet alloy with less change in the composition by preferentially arranging Al among Mn, Al and C as starting materials in the vicinity of the inner wall of a crucible and melting the materials to reduce the erosion of the crucible wall.
CONSTITUTION: Al1 amont Mn2, Al1 and C3 as starting materials and additives added as required is preferentially arranged along the inner wall of a crucible 4, and the materials are melted. By this method, the direct contact of molten Mn2 with the crucible 4 is avoided to prevent the erosion of the crucible 4 due to the Mn2. Accordingly, the crucible 4 can be used repeatedly, and an Mn-Al-C magnet alloy with less change in the composition can be obtd. easily.
