摘　　要：用化学共沉淀法合成钴铁氧体微粉,并经过不同温度处理后,对合成的样品进行X射线衍射物相分析。用扫描电子显微镜观察了颗粒的形貌,用振动样品磁强计测量了室温下粉体的磁性能。结果表明:随着热处理温度升高,颗粒长大;样品的饱和磁化强度也随着热处理温度的升高而增加。Co-ferrite Fine Powder was synthesized by chemical co precipitation method.After heating treatment at different temperatures;the phase structure of Co-ferrite samples was researched by XRD.SEM was used to observe the morphology of the powders grain.VSM was used to measure the magnetic parameters of samples at room temperatures.The results showed that the average size increased with the increasing of the heat treatment temperatures.The saturation magnetizability increased as the heat treatment temperatures i...
