Mn - Zn 페라이트 단결정과 접합유리와의 계면반응이 자기적특성에 미치는 영향

다국어 초록 (Multilingual Abstract)

The effect of interface reaction between Mn-Zn ferrite single crystal and 61SiO₂-23PbO-6ZnO-8Na₂0-2K₂0 (㏖%) glass on the magnetic properties of the ferrite was investigated. After the reaction, the hump of Zn concentration appeared at the ferrite adjacent to the interface. The initial permeability of the ferrite bonded with the glass at 700℃ was 1766 at 100 KHz and reduced to 907 after reaction at 1000 ℃. The permeability degradation with increasing reaction temperature was considered to be attributed not only to the size diminution of the ferrite due to the its dissolution into the glass but also to the residual stress due to the difference in expansion coefficient between the ferrite and the diffusion layer-the region of the hump of Zn concentration-adjacent to the interface.
