预烧温度对用共沉淀法制备的高导锰锌铁氧体微结构和磁性能的影响
Effects of presintering temperature on microstructure and magnetic properties of high permeability MnZn ferrites prepared by co-precipitation technology
摘要
Abstract
High permeability Mn-Zn ferrites were prepared from waste Mn-Zn ferrites by co-precipitation technology.The effects of presintering temperature on the sample's microstructure and magnetic properties were studied using XRD,SEM and BET as characterization method. The results show that with increase of the presintering temperature, the surface area of the powders reduces, the grains gradually become larger and the crystal structure tends to complete. The initial permeability of the ring increases at first then decreases as the presintering temperature increases. The optimal presintering temperature of the co-precipitation powders is 850 ℃, at this point the presintering powders have complete crystal structure and the particle size is uniform. The high permeabilityμi over 13 000 ferrites are obtained through atmosphere-control sintering.关键词
