| titleOfInvention | Secondary aggregate of metal magnetic particles for magnetic recording and method for producing the same |
| abstract | (57) [Problem] To produce a coating type magnetic recording medium, it has excellent kneading characteristics with various binder resins and organic solvents in a kneader and excellent dilution and dispersion characteristics by adding an organic solvent. The surface smoothness and squareness ratio of the obtained magnetic coating film can be further improved, and furthermore, the storage efficiency and the transport efficiency are high, and the metal magnetic particles having excellent handling performance to have good fluidity. It relates to secondary aggregates. SOLUTION: The primary particles have an average major axis diameter of 0.05-0. A magnetic recording medium comprising a secondary agglomerate composed of metal magnetic particles of 25 μm and having an average particle diameter of 300 to 800 μm, an upper limit of the particle diameter of 2000 μm, and a repose angle of 38 to 45 degrees. The secondary aggregate of the metal magnetic particles for use is obtained by crushing the granulated metal magnetic particles with a device having a function of crushing with a rotor and a function of forcing the particles to pass through a screen. |
