PURPOSE:To obtain a magnetic alloy powder contg. a rare-earth metal excellent in magnetic characteristics by a reduction/diffusion method. CONSTITUTION:The mixture of a metallic Ca powder, a rare-earth oxide powder and a metallic material to control the maximum thickness to 30mum is molded, the molded mixture is heat-treated in an inert gas atmosphere or in vacuum, the by-produced CaO and the Ca remaining in the reaction product are removed, the obtained metal grain is crushed, and an alloy powder contg. the rare-earth metal is produced. |
