PROBLEM TO BE SOLVED : To provide the composition for a rare earth bond magnet and the rare earth bond magnet, of sufficient heat resistance, and high mechanical strength, with excellent recycling property. SOLUTION : The composition for rare earth bond magnet of excellent recycling property contains rare earth-transition metal bond powder and polyphenylene sulfide (PPS) resin. At least 70wt.% of the PPS resin is crosslinked PPS whose melt viscosity (measured at 300°C with shear rate 600s-1) is 200poise or higher. COPYRIGHT : (C)2006, JPO&NCIPI |
