沸腾回流法制备纳米NiZn铁氧体的研究

Nanometer NiZn ferrite powder with spinel structure was prepared by a new chemical method —— refluxing method. Refluxing time and pH value of coprecipitation were discussed based on the XRD analysis and pH value measurement. The optimum refluxing time and pH value of coprecititation were 6 hours and 9.5~11.0, respectively. Ni_0.5Zn_0.5Fe₂O₄ powder prepared by refluxing method was about 20 nm by TEM analysis. And VSM results revealed that the prepared Ni_0.5Zn_0.5Fe₂O₄ powder had typical soft magnetic characteristics.
