摘要:
这是一篇冶金工程领域的论文。锰锌尖晶石铁氧体由于其具有高磁导率和高频低损耗等优点，被广泛应用于各领域。为充分利用电炉粉尘中的Fe、Zn、Mn等元素，以碱浸法处理过的含锌电炉粉尘为原料，加入MnSO4·H2O，采用固相烧结法制备Mn-Zn尖晶石铁氧体。通过XRD、SEM-EDS、VSM等，探讨温度、配比（RZ/M）、预处理对Mn-Zn铁氧体的合成及磁性能的影响。结果表明，当反应温度升高，锰锌铁氧体中的晶粒间吞并速度加剧，饱和磁感应强度和晶粒尺寸增加，而矫顽力减小。当RZ/M变化到1∶1.0，饱和磁感应强度、矫顽力和晶粒尺寸均增加。预处理后的电炉粉尘中的SiO2含量降低，合成的锰锌铁氧体的磁饱和强度增加。因此，经过浓度为2 mol/L的碱液预处理后，在质量比为1∶1.0、煅烧温度为1 100 ℃的固相反应条件下合成的锰锌尖晶石铁氧体性能较好，其饱和磁感应强度（Ms）为17.902 emu/g，矫顽力（Hc）为3.21 kA/m。
Abstract:This is an article in the field of metallurgical engineering. Mangane-zinc spinel ferrite has been widely used in various fields due to its advantages of high permeability, high frequency and low loss. In order to make full use of Fe, Zn, Mn and other elements in electric arc furnace dust (EAFD), Mn-Zn spinel ferrite was prepared by solid phase sintering method with alkali leaching zinc-containing EAFD as raw materials and MnSO4·H2O added. The effects of temperature, mass ratio (RZ/M) and pretreatment on the synthesis and magnetic properties of Mn-Zn ferrite were investigated by XRD, SEM-EDS and VSM. The results show that with the increase of reaction temperature, the speed of inter-grain merging in the Mn-Zn ferrite increases, the magnetic saturation induction and crystal grain size increase, and the coercivity decreases. When RZ/M changes to 1∶1.0, the magnetic saturation induction, coercivity and grain size increase. After pretreatment, the content of SiO2 in the EAFD decreases, and the magnetic saturation strength of the synthesized manganese-zinc ferrite increases. Therefore, after pretreatment with 2 mol/L alkali solution, the performance of manganzn-spinel ferrite synthesized at the condition of mass ratio 1∶1.0 and calcination temperature 1 100 ℃ is the best. Its saturation magnetic induction intensity (Ms) is 17.902 emu/g, and coercivity (Hc) is 3.21 kA/m.
