(57) [Problem] To provide a method for manufacturing an oxide magnetic material applicable as a high-frequency material for electronic devices, magnetic tiles, and radio wave absorbers. SOLUTION: NiZn system, MgZn system or MnZn A magnetic powder (polishing sludge) is mixed with a nonmagnetic powder (industrial clay) containing 0.1% by weight or more of an organic binder. After shaping the mixture by adjusting the humidity, 100 Bake at a top temperature of 0 ° C. or higher. Thereby, NiZ The n-type and other magnetic powders can be effectively utilized without being discarded, thereby contributing to environmental conservation. |
