共沉淀法锰锌铁氧体的制备及其磁性能

Abstract

Abstract: Mn-Zn ferrite precursor powder was prepared by co-precipitation method.The Mn-Zn ferrite was obtained by sintering after being pressed,and its particle size of ferrite precursor was analyzed.XRD and magnetic properties of Mn-Zn ferrite were tested and analyzed.Results showed that uniformly distributed nano-particles can be obtained by chemical co-precipitationmethod under suitable conditions.After sintering,the sample is in a single phase of Mn-Zn ferrite spinel.The prepared Mn-Zn ferrite possessed high magnetic susceptibility and standard hysteresis loop.The magnetic susceptibility of ferrite increased gradually with the zinc volume reducing and the iron content increasing.

Key words: co-precipitation, Mn-Zn ferrites, magnetic susceptibility, hysteresis loop
