电解锰渣制备SiO2掺杂锰锌铁氧体
Preparation of SiO2 Doped Mn-Zn Ferrite from Electrolytic Manganese Residue
摘要
Abstract
Mn-Zn fertile powders have been produced from Electrolytic Manganese Residue (EMR) via chemical co-precipitation method combined with ceramic method after leaching EMR in sulfuric acid and purifying the obtained solution. The effect of temperature on synthesis ratio of precursor was studied. The crystalline phases and the specific surface area of the SiO2-doped samples were characterized respectively by X-ray diffraction (XRD) and Specific-surface-area Instrument of Brunauer-Emmett-Teller (BET). In addition, the magnetic measurements were carried out on vibrating sample magnetometer ( VSM). The results showed that synthesis ratio of precursor can reached up to 87. 9% at the temperature of 50 ℃. Specific surface area of the Mn-Zn Ferrite samples were significantly improved with SiO2 doping. The optimal sample was obtained with a saturation magnetization of 71.95 emu/g, a coercivity of 10.49 G and a remanent magnetization of 1.32 emu/g when SiO2 doped was 0.45%.关键词
