Abstract
The low temperature sintering of Ni-Zn-Cu ferrite has been investigated by usual ceramic technique. The sintering
density and the permeability of the sintered ferrite were strongly affected by the size of the starting oxide powders and the
pre-sintering temperature. It was most effective to utilize fine particles of iron oxide and to calcine at about 800°C for the
preparation of high permeability ferrite. The sintered ferrite with a density greater than 4.5g/cc and the permeability at 10MHz
greater than 200 was obtained at relative low sintering temperature, (about 900°C). This condition is suitable for multilayer
chip inductor application.
