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 covering material:

High purity nano alumina is related to the favorable and also unfavorable diaphragm of lithium battery as a ceramic layer, which plays the duty of heat resistance, heat resistance and insulation, so as to protect against the power battery from short circuit due to high temperature as well as diaphragm melting.

Ingredients for cathode materials of lithium batteries:

High purity nano-alumina doped with lithium cobalt and lithium manganate can enhance thermal security, cycle performance and overcharge resistance, inhibit the formation of oxygen and also the decay of LiPF6, prevent straight call between LiCo02 and also electrolyte, decrease the loss of electrochemical details capability, as well as improve the electrochemical specific ability of LiCoO2.

Driver provider:

High purity γ-type nano-alumina is a permeable material with an internal area of thousands of square meters per gram, high activity and strong adsorption capacity. It is a commonly utilized adsorbent, stimulant and also catalyst service provider in oil refining and also petrochemical sector; it is a deacidizing agent for transformer oil and also generator oil in industry, as well as it is also utilized for chromatographic analysis; it is a neutral and solid desiccant busy, its drying out capability is no much less than that of phosphorus pentoxide, and it can be restored and also reused after heating below 175 ℃ for 6-8 hours.

Powder finishing anti-caking:

In summer season, nano-alumina can effectively stop powder covering caking. Nanometer light weight aluminum trioxide utilized in powder coatings can enhance the fluffiness of powder coatings and also have good anti-caking impact. It has good storability for powder layers utilized in high temperature and also high moisture atmosphere.

Covering, rubber, plastic wear-resistant as well as hardening representative:

Adding 5-20% nano-alumina, the covering can significantly enhance the wear resistance and scrape resistance of the finish, which is 2-5 times more than that of the typical coating. After nano-alumina is added to the paint, an extremely fine, uniform as well as hard network framework can be formed on the paint surface, which shields the polymer paint layer from damage. the scratch resistance of nano-paint is 3 times more than that of the initial paint. it is commonly made use of in auto paint and so on. The addition of nano-aluminum trioxide can dramatically improve the hardness of the layer, and concerning 20% can get to 6-7H. The transparency of the layer is not impacted.

Plastic, rubber, adhesive, 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 material matrix and fillers, enhance the thermal conductivity of matrix products and not minimize its mechanical buildings, surface treatment representatives such as coupling agents are typically utilized to improve the thermal conductivity.


Nano alumina has high purity, uniform particle size and also great diffusion. When around 10% alumina is added to the sintered porcelains, the creating stress boosts, which can reduce the variety of pores, therefore raise the thickness of the ceramic blank, boost the thickness as well as mechanical properties of the sintered alumina ceramics, and minimize the sintering temperature more effectively.

Powder metallurgy:

Nano alumina for metallurgy has little particle dimension, huge details area as well as high activity, adding 1-3% nano-alumina to prevent matrix densification as well as grain size, improve hardness, boost electric conductivity and mechanical buildings, and enhance melting factor as well as heat resistance.

Sprucing up:

Alumina bits are uniform, have high sphericity, and also are precision brightening powder, is an excellent product for metallographic sprucing up, but likewise appropriate for stainless-steel mirror polishing, titanium polishing, cast iron polishing, aluminum mirror sprucing up, stone mirror sprucing up, paint sprucing up, material sprucing up, PCB circuit card polishing, glass sprucing up, optical glass, glasses lens polishing, material lens polishing, sapphire sprucing up, LED sprucing up, germanium sprucing up. Zinc sprucing up, fast polishing, great brightness, no scrapes.

Light Weight Aluminum Oxide Price

The price is influenced by numerous aspects including the supply and also demand on the market, market trends, economic activity, market sentiment, and also unexpected events.
