Description:Good natures of Fe3O4 nanopowder: high hardness, magneticApplication of Ferroferric Oxide (Fe3O4) Nanopowder:1.Magnetic liquid: magnetic liquid is a new type functional material. 2.Catalyst: Fe3O4 nanoparticles are used as catalysts in many industrial reactions. Due to the small size and large SSA, rough surface, it increases the contact surface for chemical reactions. 3.Using Fe3O4 nanoparticles as the carrier, the catalyst components coated on the surface of the particles to form core-shell structure catalyst ultrafine particles would maintains the high catalytic performance and make the catalyst easy to recycle. 4.Magnetic recording material: Nano Fe3O4 has a very high coercivity due to its small size and magnetic structure changes from multi-domain to single-domain, it can greatly improve the signal-to-noise ratio and image quality and thus high density of information recording. 5.Microwave absorbing material: Fe3O4 magnetic nanopowder can be used as a kind of ferrite absorbing material for its high magnetic permeability.Storage Condition:Ferroferric Oxide (Fe3O4) nanopowder should be stored in sealed, avoid light, dry place. Room temperature storage is ok.SEM & XRD :
