Abstract

Abstract: The processing with a physical method by using combined-size particles to decrease firing temperature for Ni-Cu-Zn ferrite was reported. As the densification process can be accelerated by selecting suitable ratio of nano-particles and micro-particles, the firing temperature was decreased and high initial magnetic permeability was held above 700 for Ni0.13Cuo.26Zn0.64Fe1.9804 ferrite. The initial magnetic permeability of the low firing (900℃) ferrite prepared by combined-size powders with 10% nano-sized powders was 764.

Key words: soft ferrite, low sintering temperature, nano-particles
