Abstract: New sintering aids for the production of the high performance Nd-Fe-B permanent magnets were found. Powder of Rare-Earth Cobalt Boron intermetallic compound was mixed with that of Nd2Fe14B1. With the suitable proportion of blending, energy product for the magnet was achieved 45 MGOe and over, which is the highest point in mass production base. It was because the powder of Rare-Earth Cobalt Boron alloy composed of Co-based intermetallic compounds such as R1Co2, R1Co3, R1Co4B1 is so stable that Rare-Earth elements of the alloy were prevented from oxidation, which is inevitable in the case of ordinary production process.
