Magnetic functional nano-material---Spherical FE3O4 Iron Oxide black powders 100-200nm
As
a newly developing functional material, magnetic nano material always displays some different special purposes comparing with the common
magnetic materials relying on its unique physical and chemical properties. Nano-sized Iron oxide powder is one of the multi-functional
magnetic materials, which has extensive application in such aspects as magnetic
recording material, ferrofluid, catalysis, medicine and pigment etc.
HW NANO Iron oxide powder packaging: sample for 1kg per bags, and 25kg per fiber can.
In
recent years, using titanium dioxide as photocatalyst has the advantages of
high oxidation activity, good stability, and non-toxic to human health. It is a
very effective method for treating organic and inorganic pollutants in
industrial wastewater. Among them, the titanium dioxide is a suspension in the
form of fixed in the plexiglass and other materials for catalysis. The fixed
photocatalytic efficiency is obviously lower than that of the suspension
system, especially for large-scale wastewater treatment, the suspension system
is more effective. However, this suspension system is extremely difficult to recycle.
The magnetic composite photocatalyst prepared by encapsulating nano Iron oxide powder with titanium dioxide can be effectively recycled
by the function of magnetic field after the treatment of waste water, and then
the recycled catalyst can be recyclable.
Another important application of nano Iron oxide black powder is for magnetic recording materials.
Because of its small size, the nano structured Fe3O4 has a very high coercive
force that can be used as a magnetic recording material, which can not only
greatly improve the signal-to-noise ratio and the image quality but also
achieve high density of information recording.
Beside,
based on its small particle size, nanoparticles have the optical property that
conventional bulk materials don’t have, such as
nonlinear optical property, and the loss in the process of light absorption and
the light reflection ect. depending on the the size of nanoparticles. We Hongwu
International Group Ltd, with HWNANO brand, is a high-tech enterprise focusing
on manufacturing, research,development and processing of nanoparticles,
nanopowders. We have our own nano powders production base and R&D center
located in Xuzhou, Jiangsu, can supply nano sized Fe3O4 nanoparticles with small
quantity for researchers and bulk order for industry groups. So if you have any
demands about Iron oxide black powder or other nano
materials, please feel free to contact us at hwnano@xuzhounano.com. Thank you!
