The effect of Bi2O3 addition on the initial permeability of (MnZn) Fe2O4 has been studied with reference to the microstructure.It is found that the initial permeability of the ferrtite is increased, but it becomes more sensitive to the stress as Bi2O3 is added.Bi2O3 addition decreased the difference in oxygen content between the inner and outer regions of the bulkmaterial.This decrease, in oxygen variation might contribute to the increase in permeability.A new MnZn ferrite has been developed with a high initial permeabillity of 23000 at 10kHz through Bi2O3 addition and the use of an improved mixing process.
