Abstract:
A process for producing a compound to be formed into a rare earth metal resin-bonded magnet, comprising:a slurry preparation step of mixing materials containing a magnetic alloy powder of a rare earth metal alloy having a particle size of 30-250 .mu.m, a resin binder, and an organic solvent into a slurry wherein a weight ratio of the resin binder to the magnetic alloy powder in the slurry is 1/100 to 1/20; anda drying step of spraying and drying said slurry by means of a spray dryer apparatus to produce a compound having a particle size of less than 250 .mu.m and containing the magnetic alloy powder of the rare earth metal and the resin binder.
