镍锌铁氧体包覆电气石复合粉体的表征及磁性能分析

摘要

The composite powder was represented by preparing Nickel Zinc Ferrite to coat tourmaline through burning,and testing with XRD,SEM,and EDS,and their magnetic properties were also tested respectively. The results show,the tourmaline can be coated with Nickel Zinc Ferrite through burning,and the capacity the compos-ite powder being magnetized and reserving magnetism were both strengthened,reaching the goal of improving the magnetism of the surface of the tourmaline.%采用燃烧法制备镍锌铁氧体包覆电气石复合粉体，通过 XRD、SEM、EDS 等测试对复合粉体进行了表征，并分别测试了镍锌铁氧体、镍锌铁氧体包覆电气石复合粉体的磁性能。实验结果表明通过燃烧法可将镍锌铁氧体有效包覆在电气石表面。磁性能测试结果表明包覆之后复合粉体被磁化、保留磁性的能力均有所增强，达到改善电气石表面磁性的目的。
