- 글래스가 표면상에 피복된 합금 입자들을 구비하는 복합 입자들의 분말을 제조하도록 합금의 결정화 온도보다 더 낮은 연화점을 가지는 글래스를 비정질 연자성 합금 입자들 표면에 부착하며,합금 입자와 글래스를 접합하도록 글래스의 연화점 보다 더 높은 온도에서 합금의 결정화 온도보다 더 낮은 온도로 복합 입자들의 분말을 가압성형하는 것을 특징으로 하는 비정질 연자성 합금의 가압분말 성형체 제조방법.
- 제 1 항의 방법에 의해 제조된 비정질 연자성 합금의 가압분말 성형체에 있어서,상기 가압분말 성형체는 104 Hz에서의 투자율에 대한 107 Hz에서의 투자율의 비율이 0.5 이상인 것을 특징으로 하는 비정질 연자성 합금의 가압분말 성형체.
- 비정질 연자성 합금 입자의 표면에, 연화점이 상기 비정질 연자성 합금의 결정화 온도보다도 낮은 글래스층이 피복 형성되어 있는 것을 특징으로 하는 비정질 연자성 합금과 글래스의 복합 입자.
- 제 3 항에 있어서,상기 글래스층의 두께는 최대 3 ㎛인 것을 특징으로 하는 비정질 연자성 합금과 글래스의 복합 입자.
