                                                                     High Permeability Fe3O4 Magnetic Nano Powder

Spec: 100-200nm,99.8%, magnetic

Application for fe3o4 nano powder:

1. Iron oxide (Fe3O4) is an important spinel ferrite, is one of the most widely used soft magnetic material, used as the recording material, a pigment, magnetic fluid materials, catalysts, magnetic polymer microspheres Ball and electronic materials, which in the field of biotechnology and medicine also has a good prospect.

2. Another important use of Fe3O4 is used for magnetic recording materials. Fe3O4 nanoparticles because of its small size, the magnetic structure consists of a multidomain to single domain, with a very high coercivity magnetic material used to make can greatly improve the signal to noise ratio, improved image quality, and the recorded information can reach high density.

3. Nano / Fe3O4 as catalyst, photocatalytic oxidation paper industry wastewater. The results showed that the catalyst can effectively and quickly reduce wastewater CODcr, under certain conditions, the removal rate of 94%. Further, the presence of a catalyst having certain Fe3O4 magnetic, magnetic separation can be used to separate the catalyst from the system.

4. Fe3O4 magnetic nano powder due to its high permeability, can be used as a ferrite absorbing materials, used in the microwave absorption of.

5. Since biocompatibility Fe3O4 and better, and the toxic side effects, can be used in biomedical fields, such as cell labeling and separation, Fe3O4 as an enhanced developer, contrast agent research, targeted research of drugs, retinal detachment The repair surgery, the tumor magnetic embolization hyperthermia cancer treatment.
