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 finish material:

High pureness nano alumina is applied to the positive as well as unfavorable diaphragm of lithium battery as a ceramic finishing, which plays the role of heat resistance, heat resistance and also insulation, so regarding prevent the power battery from brief circuit as a result of high temperature and also diaphragm melting.

Ingredients for cathode products of lithium batteries:

High purity nano-alumina doped with lithium cobalt and lithium manganate can improve thermal security, cycle efficiency and overcharge resistance, prevent the formation of oxygen and also the disintegration of LiPF6, prevent direct get in touch with in between LiCo02 as well as electrolyte, reduce the loss of electrochemical details capacity, as well as enhance the electrochemical particular ability of LiCoO2.

Stimulant carrier:

High purity γ-type nano-alumina is a porous compound with an interior surface area of hundreds of square meters per gram, high activity and solid adsorption capability. It is a commonly used adsorbent, driver and driver provider in petroleum refining and also petrochemical sector; it is a deacidizing representative for transformer oil and also wind turbine oil in market, as well as it is additionally made use of for chromatographic analysis; it is a neutral as well as strong desiccant in the laboratory, its drying capability is no much less than that of phosphorus pentoxide, and it can be restored and also reused after home heating listed below 175 ℃ for 6-8 hrs.

Powder layer anti-caking:

In summertime, nano-alumina can successfully stop powder coating caking. Nanometer light weight aluminum trioxide utilized in powder layers can enhance the fluffiness of powder finishes and also have excellent anti-caking effect. It has great storability for powder coverings made use of in high temperature and high moisture environment.

Coating, rubber, plastic wear-resistant and also hardening representative:

Adding 5-20% nano-alumina, the layer can substantially improve the wear resistance and also scratch resistance of the coating, which is 2-5 times greater than that of the standard covering. After nano-alumina is included in the paint, a really fine, consistent as well as tough network framework can be formed on the paint surface area, which protects the polymer paint layer from damages. the scrape resistance of nano-paint is 3 times higher than that of the initial paint. it is extensively made use of in car paint and so on. The enhancement of nano-aluminum trioxide can significantly improve the firmness of the finish, as well as about 20% can get to 6-7H. The openness of the finishing is not affected.

Plastic, rubber, adhesive, paint thermal conductivity:

Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large spherical filling. In order to improve the compatibility of material matrix and also fillers, enhance the thermal conductivity of matrix materials as well as not decrease its mechanical residential or commercial properties, surface therapy agents such as coupling agents are generally used to improve the thermal conductivity.


Nano alumina has high pureness, consistent fragment dimension as well as great diffusion. When around 10% alumina is contributed to the sintered ceramics, the creating stress increases, which can decrease the variety of pores, hence enhance the density of the ceramic blank, enhance the thickness as well as mechanical buildings of the sintered alumina ceramics, and lower the sintering temperature better.

Powder metallurgy:

Nano alumina for metallurgy has tiny particle dimension, big details area and also high activity, including 1-3% nano-alumina to stop matrix densification as well as grain size, enhance hardness, improve electrical conductivity and also mechanical residential properties, as well as improve melting factor and also heat resistance.


Alumina particles are uniform, have high sphericity, and are accuracy polishing powder, is a good product for metallographic sprucing up, yet likewise appropriate for stainless-steel mirror sprucing up, titanium polishing, cast iron polishing, aluminum mirror polishing, rock mirror sprucing up, paint sprucing up, resin polishing, PCB circuit card sprucing up, glass sprucing up, optical glass, glasses lens sprucing up, resin lens polishing, sapphire sprucing up, LED sprucing up, germanium sprucing up. Zinc polishing, rapid sprucing up, excellent illumination, no scratches.
