本研究利用固態合成法製備Ni0.5-0.5xZn0.5-0.5xAxFe2O4(x=0~0.15)鐵氧體、Ni0.4Zn0.6-2xBxFe2+xO4(x=0~0.15) 鐵氧體、Ni0.4Zn0.4B0.1CxFe2.1-xO4(x=0~075) 鐵氧體、Ni0.4Zn0.4+xB0.1ExFe2.1-2xO4(x=0~0.075) 鐵氧體與Ni0.4Zn0.4+xB0.1DxFe2.1-2xO4 (x=0~0.075)鐵氧體，生胚燒結緻密後量測磁性質、電感特性與觀察其微結構。
研究中發現，在Ni0.5-0.5xZn0.5-0.5xAxFe2O4系列中，在x=0.05時有最高飽和磁化量為76.5 emu/g；Ni0.4Zn0.6-2xBxFe2+xO4系列中，在x=0.1時有最高鐵氧體飽和磁化量為82.7 emu/g；在Ni0.4Zn0.4B0.1CxFe2.1-xO4系列中，在x=0.025時有最高飽和磁化量為80.6 emu/g；在Ni0.4Zn0.4+xB0.1DxFe2.1-2xO4系列中，在x=0.025時有最高飽和磁化量為78.8 emu/g；在Ni0.4Zn0.4+xB0.1ExFe2.1-2xO4系列中，在x=0.025時有最高飽和磁化量為79.5 emu/g。
本研究發現在Ni0.4Zn0.425B0.1E0.025Fe2.05O4時，飽和磁化量為79.5 emu/g，初始導磁率在796 KHz時為319，品質因子在796 KHz為53.5，此結果可被應用於電感元件上。

Ferrites including Ni0.5-0.5xZn0.5-0.5xAxFe2O4 (x=0~0.15), Ni0.4Zn0.6-2xBxFe2+xO4 (x=0~0.15), Ni0.4Zn0.4B0.1CxFe2.1-xO4 (x=0~075), Ni0.4Zn0.4+xB0.1ExFe2.1-2xO4 (x=0~0.075) and Ni0.4Zn0.4+xB0.1DxFe2.1-2xO4 (x=0~0.075) have been prepared by solid-state reaction.
The magnetic properties and microstructural evolution of the ferrites were explored through examining the sintered samples with maximum density. Experimental results show that Ni0.5-0.5xZn0.5-0.5xAxFe2O4 ferrites with x=0.05 exhibited the highest saturated magnetization of 76.5 emu/g. Ni0.4Zn0.6-2xBxFe2+xO4 ferrites at x=0.15 reached the highest saturated magnetization of 82.7 emu/g. Ni0.4Zn0.4B0.1CxFe2.1-xO4 ferrites exhibited the highest saturated magnetization of 80.6 emu/g at x=0.025. Ni0.4Zn0.4+xB0.1DxFe2.1-2xO4 ferrites exhibit the highest saturated magnetization of 78.8 emu/g at x=0.025. Ni0.4Zn0.4+xB0.1ExFe2.1-2xO4 ferrites exhibit the highest saturated magnetization of 79.5 emu/g at x=0.025.
In the study, Ni0.4Zn0.425B0.1E0.025Fe2.05O4 ferrite showed a saturated magnetization of 79.5 emu/g, an initial permeability of 319 at 796 KHz and a quality factor of 53.5 at 796 KHz, which qualifies for use in ferrite-core inductors.
