Abstract: PURPOSE: A method for preparing a rare earth permanent magnet is provided to enhance the magnetic characteristics of a magnet by grinding the raw material powder of a rare earth permanent magnet with a wet method and then coating the surface of the powder to prevent the surface oxidation of the powder. CONSTITUTION: First, raw material powder is obtained by melting and grinding rare earth permanent magnet alloy with desired composition ratio. Then, mixture slurry is obtained by mixing the alloy powder with organic solvent and then grinding the powder. Next, the surface of the alloy powder is coated by adding at least one of oil and organic to the slurry. Then, dried powder is obtained by drying the mixture slurry. Next, a rare earth permanent magnet is formed by sintering the dried powder.
