Effects of V₂O₅ and ZrO₂ on Chipping Ratio of MnZn Ferrite Core

Abstract:

Cracking and chipping of MnZn Ferrites usually occur during the grinding process although proper additives such as V₂O₅ can restrain development of cracks. To study the mechanisms, the effects of adding V₂O₅ or ZrO₂ to MnZn ferrite were investigated by the rattler test. It was confirmed that adding V₂O₅ could improve the toughness of MnZn ferrite while addition of ZrO₂ showed opposite result. Based on micro-structure analysis, it was found that adding V₂O₅ increased ratio of intergranular fracture mode to the transgranular but adding ZrO₂ caused more transgranular cracks. Besides, V₂O₅ addition changed its grain size distribution and resulted in some larger grains. Possible mechanisms of the toughness improvement were proposed according the above findings.
