【摘要】 采用共沉淀法制备了锰锌铁氧体前驱体粉末,对其进行压块处理后,通过烧结得到锰锌铁氧体。对所制备的铁氧体前驱体的粒度、XRD、DTA进行了测试与分析,并测试分析了锰锌铁氧体的X荧光成分、XRD、居里温度。结果表明,采用化学共沉淀法,可以制得分布均匀的纳米级微粒。制得的铁氧体前躯体为单纯的草酸盐。经烧结的铁氧体的居里温度随含锌量的降低、含铁量的增加而逐渐升高。更多还原

【Abstract】 In this paper, the Mn-Zn ferrite precursor powder was prepared by co-precipitation method. The Mn-Zn ferrite was obtained through sintering. The size, XRD, DTA of the precursors of the ferrite have been tested and analyzed. The ferrite component of X fluorescence, XRD and Curie temperature were studied. The results show that the uniformly distributed nano-particles can be obtained by co-precipitation method. The ferrite precursors obtained are purely oxalate. The Curie temperature of the ferrite increased gradually with the zinc volume reducing and the iron content increasing.更多还原
