摘要
以Fe^(3+)、Zn^(2+)、Mn^(2+)金属离子溶液为原料,采用共沉淀法合成了锰锌铁氧体。研究了合成温度对产率的影响,以及锰锌铁氧体气孔率、密度、烧成温度对起始磁导率的影响。结果表明:在55℃合成温度下得到的产率最高;气孔率的存在会降低锰锌铁氧体的起始磁导率,随着密度增大,起始磁导率也增大;烧结温度对锰锌铁氧体的起始磁导率有重要影响。
The Mn-Zn ferrite was prepared by coprecipitation method using Fe^3＋, Zn^2＋ and Mn^2＋ solutions as raw materials. Effects of preparation temperature on product rate and open-pore rate, density, and sintering temperature on initial permeability were studied. The result shows the product rate is highest at the temperature of 55℃. Pores in the rings of Mn-Zn ferrites could decrease magnetic property： with open-pore rate increasing, the initial permeability of Mn-Zn ferrites was decreasing. As the density is increasing, the initial permeability is increasing, too. And sintering temperature has an important effect on the initial permeability of Mn-Zn ferrites.
