摘要：
Low-temperature-fired NiCuZn ferrites with the formula Ni(0.45)Cu(0.2)Zn(0.35)Fe(2-x)O(4-3/2x) with x values ranging from 0.00 to 0.25 in steps of 0.05 and sintered at 900 degrees C have been investigated in the present work. It was found that the content of Fe-deficiency could obviously influence the microstructure, sintering behavior, saturation magnetization, permeability and permittivity spectra properties of the ferrites. The variations were much different from those of the high-temperature-fired NiZn ferrites. And the corresponding mechanisms involved were discussed in detail. All-around consideration, the NiCuZn ferrite with 0.10 Fe-deficiency in composition had the best performances on sintering behavior and electromagnetic properties. (C) 2009 Elsevier B.V.
