| 摘 要： | 采用粉末冶金固相烧结法制备了NiFe2O4铁氧体粉体。对NiFe2O4粉体试样进行了DTA分析，研究了不同配比的NiO和Fe2O4粉末在980℃和1100℃烧结温度下的情况，对产物进行了XRD和SEM分析，结果表明：随着温度的升高（980～1100℃），烧结粉末的分散性越来越好，纯度也越来越高，NiFe2O4陶瓷粉体也逐渐显示出明显的尖晶石形貌。本研究制备尖晶石NiFe2O4陶瓷粉体的最佳工艺条件是：1100℃左右，时间为6h最好。

| Abstract: | The ferrite powder NiFe2O4 was prepared by solid state sintering method. DTA analysis was made to powder NiFe2O4. The sintering result of NiO and Fe2O3 of different mixture ratio under 980℃ and 1100℃ was studied. The XRD and SEM analysis results to product showed that the dispersity was better and purity is higher when temperature went up higher （980-1100℃）. The spinel pattern was showing gradually. The best condition to prepare spinel NiFe2O4 ceramic powder is 1100℃, time is 6h. |
