혼합원료를 급속냉각하여 비정질체를 제조하는 공정, 등온 열처리에 의해 자성상을 결정화시키는 공정 및 결정화된 자성상을 분리추출하기 위한 산처리 공정을 포함하여 구성되는 복합자성 분말의 제조방법에 있어서, 상기 비정질체가 mol%로, BaO:33.5-40.5%, B2O3:23.5-26.5%, Fe2O3:(33∼43)-X% 및 CoO:X%(X=7.2∼10.8)로 조성되는 혼합원료를 1000∼1500℃의 범위에서 용융한 후 급속 냉각하므로써 제조되는 것을 특징으로 하는 복합 자성분말의 제조방법.In the method for producing a composite magnetic powder comprising a step of rapidly cooling the mixed raw material to produce an amorphous body, a process of crystallizing the magnetic phase by isothermal heat treatment, and an acid treatment process for separating and extracting the crystallized magnetic phase, The amorphous body is mol%, BaO: 33.5-40.5%, B 2 O 3 : 23.5-26.5%, Fe 2 O 3 : (33-43) -X%, and CoO: X% (X = 7.2-10.8). A method of producing a composite magnetic powder, characterized in that it is produced by melting the mixed raw material to be formulated in the range of 1000 to 1500 ℃ and rapid cooling. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
