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 material:

High pureness nano alumina is put on the favorable as well as negative diaphragm of lithium battery as a ceramic finish, which plays the role of warm resistance, heat resistance and also insulation, so regarding prevent the power battery from short circuit due to high temperature and also diaphragm melting.

Ingredients for cathode materials of lithium batteries:

High pureness nano-alumina doped with lithium cobalt and lithium manganate can improve thermal security, cycle performance and also overcharge resistance, inhibit the development of oxygen as well as the decay of LiPF6, stay clear of direct contact in between LiCo02 and electrolyte, reduce the loss of electrochemical details ability, as well as improve the electrochemical particular capability of LiCoO2.

Stimulant service provider:

High pureness γ-type nano-alumina is a permeable compound with an inner surface of hundreds of square meters per gram, high activity and strong adsorption capability. It is a typically used adsorbent, driver as well as driver carrier in oil refining and petrochemical sector; it is a deacidizing representative for transformer oil and wind turbine oil in industry, as well as it is also utilized for chromatographic evaluation; it is a neutral and solid desiccant in the laboratory, its drying out capability is no less than that of phosphorus pentoxide, and it can be regenerated and also recycled after home heating listed below 175 ℃ for 6-8 hours.

Powder covering anti-caking:

In summer, nano-alumina can properly avoid powder coating caking. Nanometer aluminum trioxide made use of in powder coatings can enhance the fluffiness of powder layers and have excellent anti-caking result. It has excellent storability for powder coatings utilized in high temperature and high humidity atmosphere.

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

Adding 5-20% nano-alumina, the layer can substantially boost the wear resistance and scrape resistance of the coating, which is 2-5 times greater than that of the standard finish. After nano-alumina is added to the paint, a really fine, uniform and difficult network structure can be formed on the paint surface area, which safeguards the polymer paint layer from damages. the scratch resistance of nano-paint is 3 times more than that of the initial paint. it is extensively made use of in car paint and so on. The addition of nano-aluminum trioxide can substantially improve the hardness of the coating, and also about 20% can get to 6-7H. The openness of the finishing is not influenced.

Plastic, rubber, glue, paint thermal conductivity:

Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, huge round dental filling. In order to boost the compatibility of resin matrix as well as fillers, improve the thermal conductivity of matrix materials and also not minimize its mechanical homes, surface therapy representatives such as combining representatives are typically used to boost the thermal conductivity.


Nano alumina has high pureness, consistent fragment size and also good diffusion. When around 10% alumina is contributed to the sintered ceramics, the developing pressure boosts, which can reduce the variety of pores, therefore raise the thickness of the ceramic blank, boost the thickness and also mechanical residential properties of the sintered alumina ceramics, as well as reduce the sintering temperature level more effectively.

Powder metallurgy:

Nano alumina for metallurgy has small particle dimension, huge certain area and also high task, including 1-3% nano-alumina to prevent matrix densification as well as grain size, boost solidity, boost electric conductivity and mechanical residential or commercial properties, as well as boost melting factor and high temperature resistance.


Alumina bits are consistent, have high sphericity, as well as are accuracy brightening powder, is a good material for metallographic polishing, but likewise appropriate for stainless steel mirror sprucing up, titanium polishing, cast iron polishing, light weight aluminum mirror polishing, stone mirror polishing, paint polishing, material sprucing up, PCB motherboard polishing, glass polishing, optical glass, glasses lens sprucing up, material lens sprucing up, sapphire polishing, LED sprucing up, germanium polishing. Zinc sprucing up, fast polishing, great illumination, no scratches.
