Paper Title:
Magnetic Properties of Ni-Zn Ferrite Ceramics Prepared from the Blend of Powders
  Abstract

Ni-Zn ferrite ceramics were prepared from the blend of nano-sized powders and ultra-fine particles at the relative low sintering temperature (≤1200°C). The microstructure of the as-sintered samples characterized by SEM indicated that this process obstructed abnormal grain growth which often appeared in the Ni-Zn ferrite ceramics sintered from the nano-sized powders. The result of VSM measurements showed that the ratio of nano-sized powders to ultra-fine particles effected the initial permeability (μi) of the as-sintered samples. Optimum initial permeability can be obtained by adjusting the ratio as 1:1.
