Microstructure control of NiCuZn ferrites for multilayer-ferrite chip-components
- TDK Corporation, Chiba (Japan)
The effect of microstructure on the electromagnetic properties of low temperature sintering NiCuZn ferrite has been studied with special reference to the dissociation behavior of CuO from ferrite. The dissociation behavior was found to be greatly affected by the ambient atmosphere during ball milling. Milling under non-oxidizing conditions brought about segregation of CuO from ferrite, and a corresponding deterioration of electromagnetic properties. It is thought that the oxidation of Fe contamination (Fe(OH){sub 2}) causes the reduction of Cu{sup 2+} and separates CuO from ferrite. Relationships between the mechano-chemical reaction and resulting microstructure, the magnetic characteristics will be also discussed.
