摘要
用化学共沉淀法和熔盐法制备了一系列NiFe2O4纳米粉体,在室温下测定了它们的磁性能,利用X衍射确定了粉体的相结构、比表面积和晶格常数,利用扫描电子显微镜观察了颗粒的形貌.结果显示,由于制备方法的差异使得粉体的各项指标都有比较明显的差异.
A series of polycrystalline NiFe204 powders were preparedby chemical coprecipitation and soluble salt method, respectively. The magnetic property of the powders was characterized using Vibrating Sample Magnetometer. Their phase structure, specificsurface area and lattice constanf were presented by X-ray diffractometer. In addition, the morphologies of the powders grain were observed by Scan electron microscope. The results showed that there are evident differences of properties among the samples prepared by different ways.
