Doped iron-based nanocrystalline powder ferrite magnetic material and preparation method thereof
The invention discloses a doped iron-based nanocrystalline powder ferrite magnetic material and a preparation method thereof. The doped iron-based nanocrystalline powder ferrite magnetic material is prepared from the following raw materials in parts by mass: 60 to 65 parts of iron oxide, 10.5 to 13 parts of zinc oxide, 8 to 15 parts of magnesium oxide, 1 to 5 parts of nickel oxide, 1.5 to 4 parts of manganese oxide, 1.6 to 3.5 parts of copper oxide, 0.8 to 1.7 parts of bismuth oxide, 0.5 to 1.2 parts of silicon oxide, 0.5 to 1.2 parts of vanadium oxide and 0.5 to 1.2 parts of aluminum oxide. And 1-6 parts of iron-based nanocrystalline powder. Through specific selection of specific components and parts by weight of the components, a low sintering temperature (not more than 1200 DEG C) can be adopted in the sintering process, and the ferrite material is obtained. The obtained ferrite material has high magnetic conductivity (inductance value) and voltage resistance value (breakdown resistance), and can be used in a high-frequency range of 1MHz-100MHz.
本发明公开了一种掺杂铁基纳米晶粉末铁氧体磁性材料及其制备方法，该掺杂铁基纳米晶粉末铁氧体磁性材料由以下质量组分的原料制备而成：60份‑65份氧化铁、10.5份‑13份氧化锌、8份‑15份氧化镁、1份‑5份氧化镍、1.5份‑4份氧化锰、1.6份‑3.5份氧化铜、0.8份‑1.7份氧化铋、0.5份‑1.2份氧化硅、0.5份‑1.2份氧化钒、0.5份‑1.2份氧化铝、1份‑6份铁基纳米晶粉末。通过对各组分的具体成分及重量份数的特定选择，而在烧结过程中能够采用较低的烧结温度(不超过1200℃)，得到铁氧体材料。得到的铁氧体材料具有高的磁导率(电感值)和耐压值(抗击穿能力)，能够满足1MHz‑100MHz的高频范围内使用。
