摘要： PURPOSE: To obtain a rare earth magnet at a low cost without receiving the restriction on the form of a raw material by placing a rare earth metallic oxide on the molten Co metal melted in an induction furnace, reducing the oxide in an inert gaseous atmosphere and penetrating the rare earth metal into the molten metal.
CONSTITUTION: The Co or Co alloy is maintained at the temp. higher by 40W60°C than the m.p. thereof in the induction furnace and the oxide of 1 or ≥2 kinds of rare earth metals (mainly Sm, Ce, Pr) is made to exist on the molten metal. When the oxide is heated to the red hot state, a reducing agent (selected from Ca, CaH
2 and Mg) is added thereto in an inert gaseous (gaseous Ar) atmosphere to reduce the oxide and to penetrate the formed rare earth metal into the molten metal. The Co alloy is the alloy of Co and 1 or ≥2 kinds among Fe, Zr, Cu, Ni, Si, Ti, Mn, V, Nb, Cr, Mo and Hf. The rare earth magnet is thus produced by a simple stage.
