Manganese zinc ferrite material and preparation method thereof
The invention provides a manganese zinc ferrite material and a preparation method thereof. The manganese zinc ferrite material comprises the following main components: 51.30 to 51.78 mol% of Fe2O3, 11.42 to 11.64 mol% of ZnO, 36.58 to 37.27 mol% of MnO and 0.02 to 0.1 mol% of CoO, and the balance of Fe and inevitable impurities, and the auxiliary components comprise 200 to 2,000 ppm of CaCO3, 200 to 2,000 ppm of Bi2O3, 200 to 2,000 ppm of MoO, 200 to 2,000 ppm of NbO and 200 to 2,000 ppm of ZrO. The material has a high Curie temperature higher than 230 DEG C and Bs (25 DEG C) higher than 530 mT, and the magnetic conductivity can achieve high magnetic conductivity and low temperature coefficient within the temperature range of 0-230 DEG C. The manganese-zinc ferrite material provided by the invention can stably work under wider and more extreme environmental conditions, and the application range of manganese-zinc ferrite in the field of electronic devices is greatly widened.
本发明提供了一种锰锌铁氧体材料及其制备方法。该锰锌铁氧体材料包括主成分Fe2O351.30～51.78mol％，ZnO11.42～11.64mol％，MnO36.58～37.27mol％，CoO0.02～0.1mol％；和辅助成分CaCO3：200～2000ppm，Bi2O3：200～2000ppm，MoO：200～2000ppm，NbO：200～2000ppm，ZrO：200～2000ppm。该材料具有大于230℃的高居里温度，高于530mT的Bs(25℃)，并且在0～230℃的温度范围内磁导率能够实现高磁导率和低温度系数。本发明提供的锰锌铁氧体材料可以实现在更宽、更极端环境条件下的稳定工作，极大地拓宽了锰锌铁氧体在电子器件领域的应用。
