What is Alumina Nanoparticle used for

If you are looking for high-quality products, please feel free to contact us and send an inquiry, email:

Lithium battery diaphragm finishing product:

High purity nano alumina is put on the favorable and unfavorable diaphragm of lithium battery as a ceramic finishing, which plays the role of heat resistance, heat resistance and also insulation, so regarding protect against the power battery from short circuit as a result of heat and diaphragm melting.

Ingredients for cathode materials of lithium batteries:

High purity nano-alumina doped with lithium cobalt and lithium manganate can improve thermal security, cycle efficiency and also overcharge resistance, inhibit the formation of oxygen as well as the decay of LiPF6, prevent direct contact between LiCo02 as well as electrolyte, reduce the loss of electrochemical certain capacity, and boost the electrochemical details capability of LiCoO2.

Driver provider:

High purity γ-type nano-alumina is a porous material with an inner surface of hundreds of square meters per gram, high activity and strong adsorption capability. It is a commonly used adsorbent, driver as well as stimulant carrier in petroleum refining as well as petrochemical market; it is a deacidizing representative for transformer oil as well as turbine oil in industry, and also it is also made use of for chromatographic evaluation; it is a neutral as well as solid desiccant in the laboratory, its drying capability is no much less than that of phosphorus pentoxide, as well as it can be regenerated and recycled after heating listed below 175 ℃ for 6-8 hours.

Powder finish anti-caking:

In summer, nano-alumina can effectively prevent powder finish caking. Nanometer aluminum trioxide made use of in powder coatings can enhance the fluffiness of powder coatings and have great anti-caking impact. It has great storability for powder coverings utilized in heat and also high moisture environment.

Layer, rubber, plastic wear-resistant as well as hardening agent:

Adding 5-20% nano-alumina, the finishing can substantially enhance the wear resistance and also scrape resistance of the finish, which is 2-5 times higher than that of the conventional coating. After nano-alumina is contributed to the paint, an extremely fine, uniform and difficult network structure can be formed on the paint surface, which secures the polymer paint layer from damage. the scratch resistance of nano-paint is 3 times higher than that of the initial paint. it is extensively used in automobile paint and more. The addition of nano-aluminum trioxide can considerably improve the solidity of the finishing, and about 20% can get to 6-7H. The transparency of the finish is not affected.

Plastic, rubber, glue, paint thermal conductivity:

Alumina solitary crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, big round dental filling. In order to boost the compatibility of resin matrix and fillers, enhance the thermal conductivity of matrix products and also not minimize its mechanical residential or commercial properties, surface area therapy representatives such as coupling representatives are commonly utilized to boost the thermal conductivity.


Nano alumina has high pureness, consistent particle size and good diffusion. When about 10% alumina is included in the sintered porcelains, the creating stress increases, which can lower the variety of pores, thus increase the thickness of the ceramic blank, improve the density and also mechanical buildings of the sintered alumina ceramics, and reduce the sintering temperature level better.

Powder metallurgy:

Nano alumina for metallurgy has tiny particle size, large particular area and also high activity, adding 1-3% nano-alumina to prevent matrix densification and also grain size, improve firmness, enhance electrical conductivity and also mechanical residential properties, and improve melting factor and also high temperature resistance.


Alumina particles are uniform, have high sphericity, and also are precision brightening powder, is a good material for metallographic sprucing up, but likewise ideal for stainless steel mirror polishing, titanium sprucing up, cast iron polishing, aluminum mirror polishing, stone mirror polishing, paint polishing, resin sprucing up, PCB motherboard polishing, glass polishing, optical glass, glasses lens polishing, material lens polishing, sapphire sprucing up, LED polishing, germanium sprucing up. Zinc polishing, quick sprucing up, good brightness, no scrapes.
