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.
