Abstract
The effdct of microstructure on the electromagnetic properties of low temperature sintered NiCuZn ferrite has been studied with special reference to the dissociation behavior of CuOx from ferrite. The dissociation behavior is greatly affected by the ambient atmosphere during ball milling. The milling under non-oxidizing condition brings about not only the separation of CuOx from ferrite but also the deterioration of electromagnetic properties. It is thought that the oxidation of Fe contamination causes the reduction of Cu2+ and separates CuOx(x<1) from ferrite. Nano-structure of the sintered NiCuZn ferrite will be also discussed.
