Relationship between Magnetic Properties and Microstructures of Multilayer Ferrite

Abstract

Two kinds of NiCuZn ferrites were prepared through the multilayer process using doctor blade method and the conventional dry pressing method. These have a difference only in a molding process, relationship of the bulk density and the sintering temperature showed almost the same tendency. However, these had large differences in microstructure. The mechanical properties and the magnetic properties of these ferrites were investigated, the results show that the mechanical properties depend on pore sizes and that the magnetic properties depend on grain size distribution.
