FERRITE MAGNETIC BODY AND MANUFATURE THEREOF

摘要

PURPOSE:To prevent magnetic characteristic and mechanical strength deterioration which occur when baking contraction is suppressed in order to improve the dimensional accuracy of the baked body and provide a ferrite magnetic body which allows excellent magnetic characteristics and mechanical strength with extremely low coefficient of contraction by the ferrite magnetic body for inductance components and its manufacture. CONSTITUTION:Highly crystalline ferrite powder 1, which has La ingredient more on the surface of the crystal than in the crystal grain, is bonded by glass material 2 by mixing the highly crystalline ferrite powder 1 with La2O3 powder and glass powder and baking them.
