| titleOfInvention | Method for producing particles for permanent magnet |
| abstract | An object of the present invention is to provide a method for producing permanent magnet particles which has high magnetic properties and can be produced easily and at low cost. A method for producing particles for permanent magnets according to the present invention has a structure in which a hard magnetic phase and a soft magnetic phase that do not form a solid solution with each other are composited, and one phase is used as a core and the other phase is used as a core. The hard magnetic phase has an R—Fe—N or R—Fe—B (R is a rare earth) composition, and is composed of a soft magnetic phase. Are prepared by adding a permanent magnet particle having a Fe, Fe-M (M is a transition metal) or Fe-N composition to a solution of a surfactant and an organic solvent in an aqueous solution of a transition metal chloride, a rare earth metal chloride and boron chloride. It comprises a first step of forming a water-in-oil microemulsion by dropping an aqueous solution, a second step of forming fine particles by dropping ammonia as a fine particle forming agent, and a third step of reducing the fine particles with Ca.
