| titleOfInvention | Magnetic particle powder for magnetic recording and method for producing the same |
| abstract | (57) [Summary] (Modified) [Objective] To provide a magnetic particle powder having excellent dispersibility, which is suitable as a magnetic particle powder for high density recording. [Configuration] As = K 1 M molecular weight dependent parameters in alpha alpha is Al on the particle surfaces of the magnetic particles in 0.50 above, S i or oxides containing these, hydroxides and Zr, Ti, H f, the magnetic particle powder for magnetic recording having one or more oxides or hydroxides in Mo adhered thereto, an alkaline aqueous solution is added to an aqueous suspension of magnetic particles, and the pH value is set to 10 or more, Al, Si or these and Zr, Ti, An aqueous solution containing one or more of Hf and Mo is added and stirred, and the pH value of this solution is adjusted to near neutrality, and Al, Si or these and one or more waters of Zr, Ti, Hf, and Mo. The oxide is rapidly precipitated, and the magnetic particles in the liquid are separated by filtration together with the hydroxide to obtain a mixture of the magnetic particles and the hydroxide, which is washed with water, dried, and then compacted and pulverized with an edge runner. |
