Application of nano alumina powder in various fields


Coating material for lithium-ion battery diaphragms

:

high-purity nano-alumina

The ceramic coating is applied to the negative and positive electrode separators of the lithium batteries. It acts as insulation and heat resistance. The battery is melted and then short-circuited.

Material additive for the lithium battery cathode

Doping lithium cobaltate and lithium manganate with high-purity nanoalumina It can increase thermal stability, cycle performance and resistance to overcharge, inhibit the creation of oxygen, and prevent LiCo02 direct contact with electrolyte decreases electrochemical specific capacities, thus increasing LiCoO2.


Catalyst transport

High-purity nano-alumina g-type is porous with high activity and great adsorption. It’s a common adsorbent in petroleum refining, petrochemical, and other industries.


Powder coating Anti-caking

The nano-alcohol is used to enhance the bulkiness of powder coats. It also has an anti-caking property. High humidity and temperature environments require powder coatings with good storage properties.

Add 5-20% of nanoalumina powder to your coating. The coating will be 22 more scratch-resistant than a traditional one. 5 times. Nano-alumina is added to paint. This creates a network structure that protects the polymer paint layers from any damage. It has an anti-scratch property that is superior to the original. The strength of the paint has been increased three times. This is why it is used extensively in paints for cars and other automotive applications. The coating can be made harder by adding nano-alumina. This can make it as hard as 6-7H. This does not impact the coating’s transparency.


Thermo conductivity: Plastics, rubbers. Adhesives, and coatings.

The thermal conductivity for alumina single crystal is 30, with a high thermal conductivity and large spherical filled. Coupling agents, which are surface treatments that improve the thermal conductivity and compatibility of resin matrix and filler without altering its mechanical properties, are often used.


Ceramic

The Nano Alumina is high-purity, consistent particle size and excellent dispersibility. By adding about 10% more sintered ceramics, you can increase the molding pressure, reduce the number pores and improve the mechanical properties and density of ceramics after sintering.


Powder metallurgy

Alumina nanopowder for metalurgical use, with a small particle size, large surface area, and high activity. Nano-alumina can be added to prevent matrix density and increase in grain size. It also enhances electrical conductivity and mechanical property.


Polishing

Alumina’s uniform particle size is a sign of its high sphericity. This powder is ideal for precision polishing and can be used to polish metals. You can use it for polishing stainless steel mirrors, casting iron polishing or aluminum mirrors, and also stone mirror polishing. You can use it for: Paint polishing; resin polishing; PCB circuit board Polishing; glass polishing.
