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 layer product:

High pureness nano alumina is related to the positive and also adverse diaphragm of lithium battery as a ceramic covering, which plays the duty of heat resistance, high temperature resistance as well as insulation, so as to avoid the power battery from brief circuit due to high temperature and diaphragm melting.

Additives for cathode products of lithium batteries:

High purity nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal security, cycle efficiency and overcharge resistance, prevent the development of oxygen and also the decomposition of LiPF6, avoid direct get in touch with between LiCo02 and electrolyte, lower the loss of electrochemical specific capability, and also boost the electrochemical particular capability of LiCoO2.

Driver carrier:

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

Powder finish anti-caking:

In summer season, nano-alumina can efficiently prevent powder finishing caking. Nanometer light weight aluminum trioxide used in powder coverings can enhance the fluffiness of powder coatings and also have great anti-caking result. It has good storability for powder layers utilized in high temperature and high moisture atmosphere.

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

Adding 5-20% nano-alumina, the finish can substantially boost the wear resistance and scrape resistance of the finish, which is 2-5 times higher than that of the typical finish. After nano-alumina is added to the paint, a really great, consistent and difficult network framework can be formed on the paint surface area, which secures the polymer paint layer from damage. the scratch resistance of nano-paint is 3 times greater than that of the original paint. it is commonly utilized in car paint and so forth. The enhancement of nano-aluminum trioxide can dramatically enhance the solidity of the finishing, and also regarding 20% can reach 6-7H. The transparency of the finishing is not influenced.

Plastic, rubber, glue, paint thermal conductivity:

Alumina single crystal thermal conductivity of 30, nanometer alumina, high thermal conductivity, large spherical dental filling. In order to enhance the compatibility of resin matrix as well as fillers, enhance the thermal conductivity of matrix materials as well as not minimize its mechanical homes, surface area treatment agents such as combining representatives are typically utilized to enhance the thermal conductivity.


Nano alumina has high pureness, uniform bit size as well as great dispersion. When about 10% alumina is added to the sintered porcelains, the developing stress increases, which can reduce the variety of pores, hence boost the thickness of the ceramic space, boost the density and also mechanical residential or commercial properties of the sintered alumina ceramics, and minimize the sintering temperature level better.

Powder metallurgy:

Nano alumina for metallurgy has little bit size, big particular area and high task, including 1-3% nano-alumina to prevent matrix densification and grain size, enhance firmness, boost electrical conductivity and mechanical residential properties, as well as improve melting point and also heat resistance.


Alumina particles are consistent, have high sphericity, and also are accuracy brightening powder, is a great material for metallographic sprucing up, yet additionally ideal for stainless steel mirror sprucing up, titanium sprucing up, cast iron polishing, light weight aluminum mirror sprucing up, rock mirror polishing, paint sprucing up, resin sprucing up, PCB circuit card polishing, glass sprucing up, optical glass, glasses lens sprucing up, material lens sprucing up, sapphire polishing, LED polishing, germanium polishing. Zinc sprucing up, fast sprucing up, good illumination, no scratches.
