六方板状铁氧体粉及其制造方法、以及采用该铁氧体粉的树脂组合物及成形体
摘要：
本发明的目的是提供残留磁化及保磁力比球状的硬铁氧体粒子大，且导磁率μ”在特定的频带具有极大值的铁氧体粉及其制造方法，以及提供含有该铁氧体粉的树脂组合物及采用该树脂组合物的成形体。为了实现该目的，本发明采用了含有7.8～9重量％的Sr、61～65重量％的Fe、0.1～0.65重量％的Mg的六方板状铁氧体粉及其制造方法，以及含有该铁氧体粉的树脂组合物及采用该树脂组合物的成形体等。
摘要（英）：

Objects are to provide a ferrite powder having a residual magnetization and a coercive force larger than those of spherical hard ferrite particle, and magnetic permeability µ" is maximum in a specific frequency range, a manufacturing method thereof, a resin compound containing the ferrite powder, and a molded product made from the resin compound. To achieve the objects, a hexagonal plate shaped ferrite powder containing 7.8 to 9 wt% of Sr, 61 to 65 wt% of Fe, and 0.1 to 0.65 wt% of Mg, a manufacturing method thereof, a resin compound containing the hexagonal plate shaped ferrite powder, and a molded product made from the resin compound are employed.
