摘　　要：介绍了一种采用物理方法降低Ni-Cu-Zn铁氧体材料烧结温度的工艺一粒级组配工艺。通过纳米粉体与微米粉体的合理匹配,使材料的致密化过程加速,有效地降低了材料的烧结温度,并使材料的初始磁导率保持较高值。当纳米粉体含量为10％时,Ni0.13Cu0.26Zn0.64Fe1.98O4铁氧体的烧结温度为900℃,初始磁导率达764。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 Ni0.13Cu0.26Zn0.64Fe1.98O4 ferrite. The initial magnetic permeability of the low firing (900degreesC) ferrite prepared by combined-size powders with 10% nano-sized powders was 764.
