Process for producing hexagonal-system ferrite powder |
| abstract |
A novel hexagonal-system ferrite powder having surprisingly high coercive force as well as other excellent performance characteristics is disclosed. The ferrite powder is prepared by co-precipitating ferrous hydroxide and a metal carbonate in a liquid phase under specified conditions, followed by calcinating the resulting co-precipitated product under specified temperature conditions. The ferrite powder thus obtained has a good miscibility with a plastic material and is suitable for making a composite plastic-ferrite magnet. |
