Application of High Permeability Fe3O4 Powder:

1. Iron oxide (Fe3O4) is an important spinel ferrite, one of the most widely used soft magnetic materials, used as recording materials, pigments, magnetic fluid materials, catalysts, magnetic polymer microspheres and electronic materials, They also have good prospects in the fields of biotechnology and medicine.

2. Another important use of Fe3O4 is for magnetic recording materials. Due to the small size of Fe3O4 nanoparticles, the magnetic structure is composed of multi-domain to single-domain. Magnetic materials with very high coercivity are used for manufacturing, which can greatly increase the signal-to-noise ratio and image quality, and the recorded information can reach high density.

3. Nano/Fe3O4 is used as a catalyst to oxidize paper industry wastewater by photocatalysis. The results show that the catalyst can effectively and rapidly reduce CODcr in wastewater, and the removal rate reaches 94% under certain conditions. In addition, a catalyst with a certain Fe 3 O 4 magnetic and magnetic separation can be used to separate the catalyst from the system.

4. Due to its high magnetic permeability, Fe3O4 magnetic nanopowder can be used as a ferrite absorbing material for microwave absorption.


5. Because Fe3O4 has better biocompatibility and toxic side effects, it can be used in biomedical fields, such as cell labeling and separation, Fe3O4 as an enhanced imaging agent, contrast agent research, drug targeting research, retinal detachment , Repair surgery, tumor magnetic embolization hyperthermia to treat cancer.
