Abstract: A process for producing a compound for a rare earth metal resin-bonded magnet includes: a slurry preparation step of mixing materials containing a magnetic alloy powder of a rare earth metal alloy, a resin binder, and an organic solvent into a slurry; and a drying step of spraying and drying the slurry by means of a spray dryer apparatus to produce the compound containing the magnetic alloy powder of the rare earth metal alloy and the resin binder.

Abstract: A method of mixing a powder material and a binder in a predetermined ratio and kneading the mixture so that substantially whole surface of the powder particles are covered by the binder, molding the kneaded mixture into the shapes of desired products, then removing the binder from the moldings without causing expansion or cracks in the moldings before sintering. The binder comprises one or more organic binding substances soluble to an alcohol or to an mixed solvent of an alcohol and benzene or one or more ketones and one or more organic binding substances insoluble to the alcohol or to the mixed solvent. The moldings are put in contact with the alcohol or the mixed solvent to extract the organic binding substances soluble to the alcohol or to the mixed solvent from the moldings. The organic binding substances insoluble to the alcohol or to the mixed solvent are then removed by heat-decomposition.
