Abstract :
Cover plate materials and the core-to-plate spacing were observed to significantly lower the initial permeability (μi) of the sintered Mn-Zn ferrite samples. The degradation of the μi-value correlates very well with the Zn loss from the samples. The serious Zn loss was enhanced when using Al2O3 materials as cover plate. The Al2O3 plate act as Zn-sink and the transportation in gas phase is the controlling process for Zn loss
