摘要

Graphite microspheres containing ferromagnetic metal were prepared by acid corrosion of Fe-C alloys, and their microstructure and magnetic properties were also investigated. Our result showed that graphite microsphere is magnetic whose coercivity was 201.12 Oe at room temperature. The XPS result showed that no magnetic elements were detected on the surface of graphite spheres, suggesting that the magnetism of the graphite microsphere comes from the ferromagnetic metals encapsulated in graphite sphere and not from the graphite itself. The possible formation mechanism of graphite sphere is that the magnetic particles are trapped by tortuous graphene and attached shell by shell to form a sphere.
