| Abstract: | The effect of additives on the coprecipitation preparation process was studied in this paper. The pure, nanometer MnZn ferrite crystallites with good magnetic property and a narrow grain size distribution were obtained by adding additives. And the influence of additives on the XRD patterns, magnetic properties and Curie temperature of MnZn ferrite was investigated. The results of the research indicated that: additives can make the crystal grow more perfectly and bigger, and improve the magnetic properties of the ferrite, and decrease Curie temperature. |
